Word problem questions and answers

1. A
The ratio between black and blue pens is 7 to 28 or 7:28. Bring to the lowest terms by dividing both sides by 7 gives 1:4.

2. A
At 100% efficiency 1 machine produces 1450/10 = 145 m of cloth.
At 95% efficiency, 4 machines produce 4 * 145 * 95/100 = 551 m of cloth.
At 90% efficiency, 6 machines produce 6 * 145 * 90/100 = 783 m of cloth.
Total cloth produced by all 10 machines = 551 + 783 = 1334 m
Since the information provided and the question are based on 8 hours, we did not need to use time to reach the answer.

3. D

The turnout at polling station A is 945 out of 1270 registered voters. So, the percentage turnout at station A is:

(945/1270) × 100% = 74.41%

The turnout at polling station B is 860 out of 1050 registered voters. So, the percentage turnout at station B is:

(860/1050) × 100% = 81.90%

The turnout at polling station C is 1210 out of 1440 registered voters. So, the percentage turnout at station C is:

(1210/1440) × 100% = 84.03%

To find the total turnout from all three polling stations, we need to add up the total number of voters and the total number of registered voters from all three stations:

Total number of voters = 945 + 860 + 1210 = 3015

Total number of registered voters = 1270 + 1050 + 1440 = 3760

The overall percentage turnout is:

(3015/3760) × 100% = 80.12%

Therefore, the total turnout from all three polling stations is 80.12% — rounding to 80%.

4. D
This is a simple direct proportion problem:
If Lynn can type 1 page in p minutes, then she can type x pages in 5 minutes
We do cross multiplication: x * p = 5 * 1
Then,
x = 5/p

5. A
This is an inverse ratio problem.
1/x = 1/a + 1/b where a is the time Sally can paint a house, b is the time John can paint a house, x is the time Sally and John can together paint a house.
So,
1/x = 1/4 + 1/6 … We use the least common multiple in the denominator that is 24:
1/x = 6/24 + 4/24
1/x = 10/24
x = 24/10
x = 2.4 hours.
In other words; 2 hours + 0.4 hours = 2 hours + 0.4•60 minutes
= 2 hours 24 minutes

6. D

The original price of the dishwasher is $450. During a 15% off sale, the price of the dishwasher will be reduced by:

15% of $450 = 0.15 x $450 = $67.50

So the sale price of the dishwasher will be:

$450 – $67.50 = $382.50

As an employee, the person receives an additional 20% off the lowest price, which is $382.50. We can calculate the additional discount as:

20% of $382.50 = 0.20 x $382.50 = $76.50

So the final price that the employee will pay for the dishwasher is:

$382.50 – $76.50 = $306.00

Therefore, the employee will pay $306.00 for the dishwasher.

7. D
Original price = x,
80/100 = 12590/X,
80X = 1259000,
X = 15,737.50.

8. D
We are given that each of the n employees earns s amount of salary weekly. This means that one employee earns s salary weekly. So; Richard has ‘ns’ amount of money to employ n employees for a week.
We are asked to find the number of days n employees can be employed with x amount of money. We can do simple direct proportion:
If Richard can employ n employees for 7 days with ‘ns’ amount of money,
Richard can employ n employees for y days with x amount of money … y is the number of days we need to find.
We can do cross multiplication:
y = (x * 7)/(ns)
y = 7x/ns

9. B
The distribution is done at three different rates and in three different amounts:
$6.4 per 20 kilograms to 15 shops … 20•15 = 300 kilograms distributed
$3.4 per 10 kilograms to 12 shops … 10•12 = 120 kilograms distributed
550 – (300 + 120) = 550 – 420 = 130 kilograms left. This 50
amount is distributed in 5 kilogram portions. So, this means that there are 130/5 = 26 shops.
$1.8 per 130 kilograms.
We need to find the amount he earned overall these distributions.
$6.4 per 20 kilograms : 6.4•15 = $96 for 300 kilograms
$3.4 per 10 kilograms : 3.4 *12 = $40.8 for 120 kilograms
$1.8 per 5 kilograms : 1.8 * 26 = $46.8 for 130 kilograms
So, he earned 96 + 40.8 + 46.8 = $ 183.6
The total distribution cost is given as $10
The profit is found by: Money earned – money spent … It is important to remember that he bought 550 kilograms of potatoes for $165 at the beginning:
Profit = 183.6 – 10 – 165 = $8.6

10. B
We check the fractions taking place in the question. We see that there is a “half” (that is 1/2) and 3/7. So, we multiply the denominators of these fractions to decide how to name the total money. We say that Mr. Johnson has 14x at the beginning; he gives half of this, meaning 7x, to his family. $250 to his landlord. He has 3/7 of his money left. 3/7 of 14x is equal to:
14x * (3/7) = 6x
So,
Spent money is: 7x + 250
Unspent money is: 6×51
Total money is: 14x
Write an equation: total money = spent money + unspent money
14x = 7x + 250 + 6x
14x – 7x – 6x = 250
x = 250
We are asked to find the total money that is 14x:
14x = 14 * 250 = $3500

11. D
First calculate total square feet, which is 15 * 24 = 360 ft2. Next, convert this value to square yards, (1 yards2 = 9 ft2) which is 360/9 = 40 yards2. At $0.50 per square yard, the total cost is 40 * 0.50 = $20.

You may love GMAT word problems or you may hate them, but you can’t get around them if you want to ace the GMAT Quant section. No matter what your feelings are about this problem type, though, Magoosh’s experts have put together everything you need to know (and practice!) GMAT word problems in order to master them before test day.

What to Expect from GMAT Word Problems

Think of GMAT word problems as questions that ask you to turn real-world situations into math problems. Of course, this can be a lot more complicated than it sounds. After all, it’s one thing to understand algebra in the abstract, and quite another to think about where the rubber meets the road.

Think about it this way: the reason human beings created algebra was to solve problems about real-world situations, and the GMAT loves asking math problems about numbers and about real-world situations, a.k.a. word problems! Even folks who can do algebra in the abstract sometimes find word problems challenging.

You’ll find GMAT word problems in the GMAT Quant section. How much of the GMAT is word problems? Within the Quant section, actually a whole lot! A study of official GMAT questions from actual tests show that word problems account for 58.2% of all GMAT math questions.

 
GMAT Quant concepts by frequency chart showing word problems account for 58.2% of questions - Magoosh

In other words, test-takers should anticipate a word problem cropping up (on average) in three out of every five questions you’ll see in Quant. Because of GMAT word problems’ prevalence, you can expect to see both Data Sufficiency and Problem Solving questions in this format. The question format and answer choices may look different, but the basic premise will be the same.

You may be feeling the pressure, but hang in there! If you’re worried about how to master word problems on the GMAT, keep reading for our GMAT Word Problems strategy guide.

Strategy Guide: What’s the Trick to Mastering GMAT Word Problems?

First, the disappointing news: there’s no one strategy that will work to immediately solve every word problem, every time (where would the fun in that be?). The good news: by using and combining a variety of strategies, you can put together the tools you need to ace even the most complex GMAT word problems, every single time!

With that in mind, here are the four key strategies you’ll need.

1. Translate from Words to Math

Suppose we have the following sentence in a word problem:”Three-fifths of x is 14 less than twice y squared.” How do we change words to math? Here’s a quick guide:

  1. The verb “is/are” is the equivalent of an equal sign; the equal sign in an equation is, in terms of “mathematical grammar,” the equivalent of a verb in a sentence. Every sentence has a verb and every equation has an equal sign.
  2. The word “of” means multiply (often used with fractions and percents). Ex. “26% of x” means (0.26x)
  3. The words “more than” or “greater than” mean addition. Ex. “5 greater than x” means (x + 5) and “7 more than y” means (y + 7)
  4. The words “less than” means subtraction. Ex. “8 less than Q” means (Q – 8). Notice that the first element is always subtracted: in other words, “J less than K” means (K – J).

With that in mind, let’s go back to the sentence from the hypothetical problem above.

  • “three fifths of x” means [(3/5)*x]
  • “is” marks the location of the equal sign
  • “twice y squared” means 2(y^2)
  • “14 less than twice y squared” means 2(y^2) – 14

Altogether, the equation we get is:
itgwp-p1_img1a
Using this strategy, it’s straightforward to translate from a verbal statement about numbers to an equation.

2. Learn to Work with Variables

Working with Variables Part I: Assigning Variables

 
Most GMAT word problem concern real world quantities and are stated in real world terms, and we need to assign algebraic variables to these real-world quantities.

Sometimes, one quantity is directly related to every other quantity in the problem. For example:

“Sarah spends 2/5 of her monthly salary on rent, 1/12 of her monthly salary on auto costs including gas and insurance, and 1/10 of her monthly salary automatically goes into saving each month. With what she has left each month, she spend she spends $800 on groceries and …”

In that problem, everything is related to “monthly salary,” so it would make a lot of sense to introduce just one variable for that, and express everything else in terms of that variable. Also, please don’t always use the boring choice of x for a variable! If we want a variable for salary, you might use the letter S, which will help you remember what the variable means! If we are given multiple variables that are all related to each other, it’s often helpful to assign a letter to the variable with the lowest value, and then express everything else in terms of this letter.

Improve your GMAT score with Magoosh.

If there are two or more quantities that don’t depend directly on each other, then you may well have to introduce a different variable for each. Just remember that it’s mathematically problematic to litter a problem with a whole slew of different variables. You see, for each variable, you need an equation to solve it. If we want to solve for two different variables, we need two different equations (this is a common Word Problem scenario). If we want to solve for three different variables, we need three different equations (considerably less common). While the mathematical pattern continues to extend upward from there, more than three completely separate variables is almost unheard of on GMAT math.

When you assign variables, always be hyper-vigilant and over-the-top explicit about exactly what each variable means. Write a quick note to yourself on the scratch paper: T = the price of one box of tissue, or whatever the problem wants. What you want to avoid is the undesirable situation of solving for a number and not knowing what that number means in the problem!

Practice Question
Here’s a word problem practice question that’s a bit easier than what you might see on the GMAT!

Andrew and Beatrice each have their own savings account. Beatrice’s account has $600 less than three times what Andrew’s account has. If Andrew had $300 more dollars, then he would have exactly half what is currently in Beatrice’s account. How much does Beatrice have?

Click here for a text answer and explanation

The obvious choices for variables are A = the amount in Andrew’s account and B = the amount in Beatrice’s account. The GMAT will be good about giving you word problems involving people whose names start with a different letter so that it’s easier to assign variables. We can turn the second & third sentences into equations.

second sentence: B = 3A – 600

third sentence: (A+300) = 1/2B or 2(A+300) = B

Both equations are solved for B, so simply set them equal.

3A – 600 = 2(A + 300)

3A – 600 = 2A + 600

A – 600 = 600

A = 1200

We can plug this into either equation to find B. (BTW, if you have time, an excellent check is to plug it into both equations, and make sure the value of B you get is the same!)

B = 3000

Thus, Andrew has $1200 in his account, and Beatrice, $3000 in hers.

Working with Variables Part II: Choosing Your Approach

 
When questions have variables in the answer choices, you can decide whether you’d rather take an algebraic approach or a numerical approach. Neither one of these is “better” than the other— it all depends on what works best for you.

An algebraic approach is what you most likely learned back in high school. This means that, to solve the problem, you’ll manipulate the variables according to mathematical rules. For a super-basic example, to solve ( 2x = y ), you would divide both sides by two and end up with ( x = y/2 ).

However, you could also to a numerical approach to this (and many other!) problems. This means putting numbers into both the question and the answer choices. So let’s take the previous example—which, again, is much, much easier than anything you’d see on the GMAT:

If ( 2x = y ), what is x in terms of y?

 
A. (y/20)
B. (y/2)
C. (4/y)
D. (20/y)

 
Here, you could pick a number to stand in for x in the original equation. Let’s say x is 2. If x = 2, then the original equation tells us that y = 4.

Now, plug that into the question and the answer. The question becomes: “What is 2 in terms of 4?” It’s ½, or .5. Then, look for the answer choice that gives you this answer. Plugging in the numbers, you get:

A. (y/20) = 0.2
B. (y/2) = 0.5
C. (4/y) = 1
D. (20/y) = 5

So B must be correct.

 
What does this look like in practice? For some harder examples, take a look over at Mike’s post on Variables in GMAT Answer Choices: 2 Approaches.

3. Plug in Numbers (the Smart Way)

If you choose to use the numerical approach described above, keep in mind that there are some key tips for plugging in numbers that you should use!

Here’s a quick summary of how to quick the best numbers for a particular problem:

  • Remember that the GMAT has a broad definition of “number” that goes beyond positive integers! Zero, fractions, and negatives are all included. Work on developing number sense to help select the best numbers in a given scenario.
  • For percent problems, think outside the box: GMAT test writers know lots of students pick 100. Try 500 or 1000 instead.
  • Don’t try to pick numbers for questions involving more than one percent increase or decrease.
  • Pay attention to units and convert them appropriately. This is particularly important in solutions and mixing problems!
  • Don’t pick 1 as a number—it has too many unique properties.

A separate case involving plugging in, rather than picking, numbers: When all the answer choices are numerical, one further strategy we have at our disposal is backsolving. Using this strategy, we can pick one answer, plug it into the problem, and see whether it works. If this choice is too big or too small, it guides us in what other answer choices to eliminate. Typically, we would start with answer choice (C), but if another answer choice is a particularly convenient choice, then we would start there.

4. Understand Your Strengths and Weaknesses

With all of the above strategies at your disposal, you have everything you need to improve your answers to GMAT word problems. The most efficient way to do this is to keep an error log of word problems you’ve answered wrong in your practice, then review it. As you go through, think about the following:

  • What concept or concepts was the question testing?
  • What was tricky about the wording of the question?
  • Were you already familiar with the methods used in the explanation video?
  • Once you watched the explanation video, could you explain how to solve the problem to somebody else?

Your answers to these questions can help you craft a better strategy for GMAT Math word problems, identifying exactly what you need to review to get better!

GMAT Word Problem Practice Questions

Now that you’ve learned how to approach word problems, we’ve put together a collection of them, direct from Magoosh’s product, for you to try! Video and text answers and explanations follow each question.

  1. Ann and Bob planted trees on Friday. What is the ratio of the number of trees that Bob planted to the number of trees that Ann planted?
    (1) Ann planted 20 trees more than Bob planted.
    (2) Ann planted 10 percent more trees than Bob planted.

A. Statement 1 ALONE is sufficient to answer the question, but statement 2 alone is NOT sufficient.
B. Statement 2 ALONE is sufficient to answer the question, but statement 1 alone is NOT sufficient.
C. BOTH statements 1 and 2 TOGETHER are sufficient to answer the question, but NEITHER statement ALONE is sufficient.
D. Each statement ALONE is sufficient to answer the question.
E. Statement 1 and 2 TOGETHER are NOT sufficient to answer the question.

Our task is to determine the ratio of Bob’s trees to Ann’s trees. Let’s label these numbers of trees with variables:

Bob’s trees→B, Ann’s trees→A

With these variables, we can express the ratio we want to determine:

(B/A) =?

Statement 1:
Ann planted 20 trees more than Bob planted.

Let’s translate this into an equation using A and B:

( A=B+20 )

Now we can substitute this into our ratio, replacing A:

(B/A) = ( B/(B+20) )

No matter what simplifications we make, we cannot find a numerical value for this fraction. We would need a value for B. We cannot determine the ratio. Statement 1 by itself is not sufficient.

Improve your GMAT score with Magoosh.

Statement 2:
Ann planted 10 percent more trees than Bob planted.

Let’s translate this into an equation using A and B:

(A=1.10 x B )

Again, let’s substitute this in for A in our ratio:

(B/A) = ( B/(1.10B) )

= (1/1.1 )

We found a value for the ratio of Bob’s trees to Ann’s trees. Statement 2 alone is sufficient.

  1. The Townville museum was open for 7 consecutive days. If the number of visitors each day was 3 greater than the previous day, how many visitors were there on the first day?
    (1) There were a total of 126 visitors for the 7 days.
    (2) The number of visitors on the seventh day was three times the number of visitors on the first day.

A. Statement 1 ALONE is sufficient to answer the question, but statement 2 alone is NOT sufficient.
B. Statement 2 ALONE is sufficient to answer the question, but statement 1 alone is NOT sufficient.
C. BOTH statements 1 and 2 TOGETHER are sufficient to answer the question, but NEITHER statement ALONE is sufficient.
D. Each statement ALONE is sufficient to answer the question.
E. Statement 1 and 2 TOGETHER are NOT sufficient to answer the question.

If x is the number of visitors on the first day, then:
x = # of visitors on the 1st day
x + 3 = # of visitors on the 2nd day
x + 6 = # of visitors on the 3rd day
x + 9 = # of visitors on the 4th day
x + 12 = # of visitors on the 5th day
x + 15 = # of visitors on the 6th day
x + 18 = # of visitors on the 7th day
1) Adding up the number of visitors gives us:
x + (x + 3) + (x + 9) + (x + 12) + (x + 15) + (x + 18) = 126
We could simplify and solve this for x. So Statement 1 is sufficient.
2) x + 18 = 3x
Again, we can simplify this and solve for x. So Statement 2 is sufficient.
Answer: (D)

  1. Two teachers, Ms. Ames and Mr. Betancourt, each had N cookies. Ms. Ames was able to give the same number of cookies to each one of her 24 students, with none left over. Mr. Betancourt was also able to give the same number of cookies to each one of his 18 students, with none left over. If N > 0, what is the value of N?
    (1) N<100
    (2) N > 50

A. Statement 1 ALONE is sufficient to answer the question, but statement 2 alone is NOT sufficient.
B. Statement 2 ALONE is sufficient to answer the question, but statement 1 alone is NOT sufficient.
C. BOTH statements 1 and 2 TOGETHER are sufficient to answer the question, but NEITHER statement ALONE is sufficient.
D. Each statement ALONE is sufficient to answer the question.
E. Statement 1 and 2 TOGETHER are NOT sufficient to answer the question.

This question is really about common multiples and the LCM (note that it is different than finding the set of all multiples, though!). If Ms. Ames can give each of her 24 students k cookies, so that they all get the same and none are left over, then 24k = N. Similarly, in Mr. Betancourt’s class, 18s = N.
What are the common multiples of 18 and 24?
18 = 2×9 = 2×3×3 = 6×3
24 = 3×8 = 2×2×2×3 = 6×4
From the prime factorizations, we see that GCF = 6, so the LCM is
LCM = 6×3×4 = 72
and all other common multiples of 18 and 24 are the multiples of 72: {72, 144, 216, 288, 360, …}

Statement #1: if N<100, the only possibility is N = 72. This statement, alone and by itself, is sufficient.

Statement #2: if N > 50, then N could be 72, or 144, or 216, or etc. Many possibilities. This statement, alone and by itself, is not sufficient.
Answer = (A)

  1. A certain zoo has mammals and reptiles and birds, and no other animals. The ratio of mammals to reptiles to birds is 11:8:5. How many birds are in the zoo?
    (1) there are twelve more mammals in the zoo than there are reptiles
    (2) if the zoo acquired 16 more mammals, the ratio of mammals to birds would be 3:1

A. Statement 1 ALONE is sufficient to answer the question, but statement 2 alone is NOT sufficient.
B. Statement 2 ALONE is sufficient to answer the question, but statement 1 alone is NOT sufficient.
C. BOTH statements 1 and 2 TOGETHER are sufficient to answer the question, but NEITHER statement ALONE is sufficient.
D. Each statement ALONE is sufficient to answer the question.
E. Statement 1 and 2 TOGETHER are NOT sufficient to answer the question.

A short way to do this problem. The prompt gives us ratio information. Each statement gives use some kind of count information, so each must be sufficient on its own. From that alone, we can conclude: answer = D. This is all we have to do for Data Sufficiency.
Here are the details, if you would like to see them.
Statement (1): there are twelve more mammals in the zoo than there are reptiles
From the ratio in the prompt, we know mammals are 11 “parts” and reptiles are 8 “parts”, so mammals have three more “parts” than do reptiles. If this difference of three “parts” consists of 12 mammals, that must mean there are four animals in each “part.” We have five bird “parts”, and if each counts as four animals, that’s 5*4 = 20 birds. This statement, alone and by itself, is sufficient.
Statement (2): if the zoo acquired 16 more mammals, the ratio of mammals to birds would be 3:1
Let’s say there are x animals in a “part”—this means there are currently 11x mammals and 5x birds. Suppose we add 16 mammals. Then the ratio of (11x + 16) mammals to 5x birds is 3:1.
(11x + 16)/(5x) = 3/1 = 3
11x + 16 = 3*(5x) = 15x
16 = 15x – 11x
16 = 4x
4 = x
So there are four animals in a “part”. The birds have five parts, 5x, so that’s 20 birds. This statement, alone and by itself, is sufficient.
Both statements are sufficient. Answer = D.

Teaching your pupils to solve 2-step word problems and multi-step word problems at KS2 is one of hardest parts of a mastery led approach in maths. There are several cognitive functions at play, as children have to wrestle with their knowledge of maths vocabulary, maths operations, and often basic comprehension skills.

In this article we set out some of the sorts of maths word problems pupils can expect from the KS2 maths national curriculum and look at strategies for solving them. In total we’ve provided 30 KS2 word problems to work through, showing the variety of 2-step word problems and multi-step word problems pupils are likely to encounter.

What are word problems

Word problems in maths are sentences describing a real life scenario where children must apply their maths knowledge to reach a solution or unpick the maths problem. 

To solve maths word problems children must be familiar with the maths language associated with the mathematical symbols they are used to in order to make sense of the word problem; for example: plus, more, total = add; difference, less, minus = subtract, etc.

What are two-step word problems?

Two-step word problems are problems in which two separate calculations (usually different operations) are required to reach the answer. By different operations we mean addition, subtraction, multiplication or division.

What are multi-step word problems?

Multi-step word problems are maths problems that require multiple calculations to solve them. They will usually will involve more than one operation and often more than one strand from the curriculum. For example a multi-step word problem on area and perimeter may also involve ratio and multiplication.

In KS2 SATs multi-step word problems can be awarded up to 3 marks for a correct answer, but 1 or 2 marks can be achieved by solving some of the steps in the problem correctly.

Two-step word problems and multi-step word problems pupils will encounter in KS2

In Key Stage 2, there are nine ‘strands’ of maths – these are then further split into ‘sub-strands’. For example, ‘number and place value’ is the first strand: a Year 3 sub-strand of this is to “find 10 or 100 more or less than a given number”; a Year 6 sub-strand of this is to “determine the value of each digit in numbers up to 10 million”. 

The table below shows how the ‘sub-strands’ are distributed across each strand and year group in KS2.

Strand Year 3 Year 4 Year 5 Year 6 Total
Number and place value 6 9 5 7 27
Calculations 7 8 15 9 39
Fractions, decimals and percentages 7 10 12 11 40
Ratio and proportion 0 0 0 4 4
Algebra 0 0 0 5 5
Measurement 17 9 10 8 44
Geometry: properties of shape 5 4 6 7 22
Geometry: position and direction 0 3 1 2 6
Statistics 2 2 2 2 8

As well as varying in content (sometimes by using a combination of strands in one problem, e.g. shape and calculations), word problems will also vary in complexity, from one-step to multi-step problems. 

Different word problems will provide a different level of cognitive demand as an alternative method of adapting the level of difficulty. The STA mathematics test framework (2015) sets these out.

Strand 1 2 3 4
Depth of understanding recall of facts or application of procedures use facts and procedures to solve simple problems use facts and procedures to solve more complex problems understand and use facts and procedures creatively to solve complex or unfamiliar problems
Computational complexity no numeric steps one, or a small number of numeric steps a larger number of numeric steps all steps are simple a larger number of numeric steps, at least one of which is more complex
Spatial reasoning no spatial reasoning required manipulation of the geometric information is required complex manipulation of the geometric information is required interpret, infer or generate new geometric information
Data interpretation no data interpretation required select and retrieve information select and interpret information generate or infer new information from data
Response strategy select one or more responses or construct a simple response construct a small set of responses construct a straightforward explanation shows evidence of a method construct a complex explanation

Skills required for multi-step word problems

There is a high level of cognitive demand on children when they are faced with multi-step word problems: interpreting the question to find the arithmetic behind it and then calculating the arithmetic itself.

Therefore, a secure knowledge of times tables and a confident understanding of arithmetic are essential skills for being able to successfully solve word problems.

Arithmetic within multi-step word problems

A useful strategy to use in class is to provide children with a list of arithmetic questions you have previously ‘extracted’ from some word problems. 

Generally, children are much more confident with arithmetic than word problems, so they should be able to answer these with relative ease. 

In the next lesson, give the children the word problems – after a while, ask them which they found easier and why. 

Then show the children the arithmetic from the previous day and ask if they can see the similarities. They could then try to ‘extract’ the arithmetic from word problems themselves.

How to teach multi-step word problems

Here are two simple strategies that can be applied to most two-step word problems and multi-step word problems before solving them.

  1. What do you already know?
  2. How can this problem be drawn/represented pictorially?

How to solve a year 6 multi-step word problem

Here’s an example.

There are 29 pupils in a class. The teacher has 7 litres of apple juice. She pours 215 millilitres of apple juice for every pupil. How much apple juice is left over?

1. What do you already know?
  • There are 1,000ml in 1 litre
  • Pours = liquid leaving the bottle = subtraction
  • For every = multiply
  • Left over = requires subtraction at some point
2. How can this problem be drawn/represented pictorially?

Bar modelling is always a brilliant way of representing even multi step word problems in year 6, but there are always other ways of drawing it out. For example, for this question, you could draw 29 pupils (or stick man x 29) with ‘215 ml’ above each one and then a half-empty bottle with ‘7 litres’ marked at the top.

Now to put the maths to work. This is a Year 6 multi-step problem, so we need to use what we already know and what we’ve drawn to break down the steps.

3. How to answer step by step
  • There are 29 pupils in a class.
  • The teacher has 7 litres of apple juice.  1) 7 litres = 7,000ml
  • She pours 215 millilitres of apple juice for every pupil.  2) 215ml x 29 = 6,235ml
  • How much apple juice is left over?  3) 7,000ml – 6,235ml = 765ml

How to solve a year 5 multi-step word problem

A similar approach can be used for this one.

  • Mara is in a bookshop. She buys one book for £6.99 and another that costs £3.40 more than the first book. She pays using a £20 notes. What change does Mara get?
1. What do you already know?
  • More than = add
  • Using decimals means I will have to line up the decimal points correctly in calculations
  • Change from money = subtract
2. How can this problem be drawn/represented pictorially?

See this example of bar modelling for this question:

bar-model-example-ks2

Now to put the maths to work using what we already know and what we’ve drawn to break down the steps.

3. How to answer step by step

  • Mara is in a bookshop. 
  • She buys one book for £6.99 and another that costs £3.40 more than the first book.  1) £6.99 + (£6.99 + £3.40) = £17.38
  • She pays using a £20 note. 
  • What change does Mara get?
  • £20 – £17.38 = £2.62

2-step word problems Year 3

With word problems for Year 3, children will move away from solely using concrete resources when solving word problems and start using written methods. This is also the year in which two-step problems will be introduced.

As some children may not be confident readers, it is important that word problems are explored in a variety of contexts: as a class, in groups, in partners, with an adult, with a list of ‘mathematical vocabulary’ accessible, etc. It is important that children’s literacy skills don’t hinder their progress or in maths.

2-step word problems Year 4

With word problems year 4, children should feel confident using the written method for each of the four operations. This year children will be presented with a variety of problems, including two-step problems, and be expected to work out the appropriate method required to solve each one. 

While children should be focusing on formal written methods, it is important that concrete resources and pictorial representations are still used to consolidate their understanding.

  • Mia has a jug with 2.5 litres of water in it. She pours two glasses of 300ml and three glasses of 500ml. How much water is left in the jug? Give your answer in millilitres. Answer: 400ml

Multi-step word problems: Year 5

Although one and two-step word problems are the mainstay of Year 5 reasoning and problem solving, word problems for year 5 are also when children may start to extend their range to include multi-step problems; 

In Upper Key Stage 2, word problems become more complex not only in the calculations (higher numbers, decimals etc.) but also the vocabulary – a subtlety of maths language may mean it is less obvious as to which operation is required.

In the first example below, the children are essentially being asked to add and divide by 7 – or find the ‘mean’ – but the word problem doesn’t use the vocabulary children usually associate with addition or division, such as total, sum, share, split, etc. To reduce the cognitive demand of questions such as these, the numbers could be altered so that children are still required to extract the calculations from the word problems but can then complete those calculations with simpler numbers.

Example Year 5 multi-step word problems

  • A writer is working on two projects. She has one week to write 518 maths questions for one project and 476 questions for another project. If she completes the same number of questions every day, how many should she aim to complete each day? Answer: 142
  • Walton Wanderers’ new shirt costs £29. In the first month after it was launched, the club shop sold 1,573 shirts. 54 shirts were returned because they did not fit. How much money did the club shop receive by selling the shirts? Answer: £44,051

Multi-step word problems Year 6

With word problems for year 6, children move on from 2-step word problems to multi-step word problems. These could include fractions, decimals and percentages. Some of the most complex problems in KS2 SATS papers are worth 3 marks – these are intended to challenge more able mathematicians. 

As previously mentioned, one or two marks can be achieved for correctly solving different ‘steps’ of the problem even without arriving at the correct final answer.

Fraction word problems

Fraction word problems require a good understanding of division and multiplication. Bar models or other pictorial representations are useful strategies in helping children solve problems like these.

Fraction problems appear throughout KS2. In Year 3, they will be based on seven objectives:

  • count up and down in tenths
  • recognise that tenths arise from dividing an object into 10 equal parts and in dividing one-digit numbers or quantities by 10
  • recognise, find and write fractions of a discrete set of objects: unit fractions and non-unit fractions with small denominators
  • recognise and use fractions as numbers: unit fractions and non-unit fractions with small denominators
  • recognise and show, using diagrams, equivalent fractions with small denominators
  • add and subtract fractions with the same denominator within one whole
  • compare and order unit fractions, and fractions with the same denominators.

The progression in fractions through KS2 ends in Year 6 with problems being based on seven objectives:

  • use common factors to simplify fractions and use common multiples to express fractions in the same denomination
  • compare and order fractions, including fractions > 1
  • add and subtract fractions with different denominators and mixed numbers, using the concept of equivalent fractions
  • multiply simple pairs of proper fractions, writing the answer in its simplest form
  • divide proper fractions by whole numbers
  • associate a fraction with division and calculate decimal fraction equivalents
  • recall and use equivalences between simple fractions, decimals and percentages, including in different contexts.

Decimals word problems

Decimal word problems are commonly used in questions involving money, although they also often appear alongside fractions and/or percentages, requiring children to calculate their equivalences.

Decimal problems begin in Year 4 and will be based on six objectives:

  • recognise and write decimal equivalents of any number of tenths or hundredths
  • recognise and write decimal equivalents to ¼, ½, ¾
  • find the effect of dividing a one- or two-digit number by 10 and 100, identifying the value of the digits in the answer as ones, tenths and hundredths
  • round decimals with one decimal place to the nearest whole number
  • compare numbers with the same number of decimal places up to two decimal places; solve simple measure and money problems involving fractions and decimals to two decimal places.

The progression in decimals from Year 4 ends in Year 6 with problems being based on six objectives

  • associate a fraction with division and calculate decimal fraction equivalents for a simple fraction
  • identify the value of each digit in numbers given to three decimal places and multiply and divide numbers by 10, 100 and 1000 giving answers up to three decimal places
  • multiply one-digit numbers with up to two decimal places by whole numbers
  • use written division methods in cases where the answer has up to two decimal places; solve problems which require answers to be rounded to specified degrees of accuracy
  • recall and use equivalences between simple fractions, decimals and percentages, including in different contexts.

  • A teaspoon contains 5.26ml of cough medicine. Amber takes 5 teaspoons full every day. How many millilitres of cough medicine does Amber take each day? Answer: 26.3ml

Percentage word problems

Children need a secure understanding in fractions before attempting percentage problems; they are therefore not introduced until Upper Key Stage 2. Percentage word problems begin in Year 5 and will be based on two objectives:

  • recognise the per cent symbol (%) and understand that per cent relates to ‘number of parts per hundred’, and write percentages as a fraction with denominator 100, and as a decimal
  • solve problems which require knowing percentage and decimal equivalents of ½, ¼, 1/5, 2/5, 4/5 and those fractions with a denominator of a multiple of 10 or 25.

The progression in percentage continues into Year 6 with problems being based on two objectives:

  • recall and use equivalences between simple fractions, decimals and percentages, including in different contexts
  • solve problems involving the calculation of percentages and the use of percentages for comparison.

Percentage multi-step word problem: Year 6

  • Rachel and Max are playing a computer game. The game has 160 levels. Rachel’s counter says she has completed 60% of the game. Max’s counter says that he has completed 45% of the game. What levels are they each on? Answer: Rachel = Level 96, Max = Level 72

Measurement word problems

Many measurement word problems require children to convert between metric measures, thus children should be confident in multiplying and dividing by powers of 10. More complex measurement word problems (such as those involving imperial measures) may require children to have an understanding of ratio and proportion.

Word problems involving measures begin in Year 3 and will be based on six objectives:

  • measure, compare, add and subtract: lengths (m/cm/mm); mass (kg/g), volume/capacity (l/ml)
  • time word problems where children tell and write the time from an analogue clock, including using Roman numerals from I to XII, and 12-hour and 24-hour clocks
  • estimate and read time with increasing accuracy to the nearest minute
  • record and compare time in terms of seconds, minutes and hours
  • use vocabulary such as o’clock, a.m./p.m., morning, afternoon, noon and midnight
  • know the number of seconds in a minute and the number of days in each month, year and leap year; compare durations of events

The progression continues into Year 6 with problems being based on three objectives:

  • solve problems involving the calculation and conversion of units of measure, using decimal notation up to three decimal places where appropriate
  • use, read, write and convert between standard units, converting measurements of length, mass, volume and time from a smaller unit of measure to a larger unit, and vice versa, using decimal notation to up to three decimal places
  • convert between miles and kilometres.

Measurement multi-step word problem: Year 6 (crossover with ratio)

  • 5 miles are approximately equivalent to 8 km. Mr Norton’s car speedometer shows that he is travelling at 104 km/h. About how many miles per hour (mph) is the car travelling? Answer: 65 mph

Money word problems

Problems involving money link with decimals (money notation) and measures (converting between £ and p). Where possible, especially until their understanding is secure, children should be handling real money to help them solve problems.

Money word problems begin in Year 3 and will be based on one objective: add and subtract amounts of money to give change, using both £ and p in practical contexts. The non-statutory guidance in the curriculum recommends that pupils continue to become fluent in recognising the value of coins, by adding and subtracting amounts, including mixed units, and giving change using manageable amounts.

The decimal recording of money is introduced formally in year 4, where word problems will be based on one objective: solve simple measure and money problems involving fractions and decimals to two decimal places.

Money problems continue throughout KS2 but are not specifically mentioned in the National Curriculum beyond Year 4.

Two-step money word problem: Year 6 (crossover with mixed operations)

These are the different prices of tickets at a cinema.

year 6 money

  • Jamaal’s dad buys two adults’ tickets and four children’s tickets. How much money do the tickets cost altogether? Answer: £32.20

Area word problems

Mathematical questions related to area require a secure understanding of arrays, times tables, multiplication, division and factors. Concrete resources such as Numicon and multilink can be used to support children to solve these problems.

Word problems involving area begin in Year 4 and will be based on one objective: find the area of rectilinear shapes by counting squares. The progression continues into Year 6 with problems being based on three objectives:

  • recognise that shapes with the same areas can have different perimeters and vice versa
  • recognise when it is possible to use formulae for area and volume of shapes
  • calculate the area of parallelograms and triangles

Area multi-step word problem: Year 6

  • A square has a side length of 6cm. A triangle has a base of 8cm and a perpendicular height of 7cm. What is the difference in their areas? Answer: 8cm2

Perimeter word problems

As well as being an important life skill, it is important for children to be able to measure accurately with a ruler for some aspects of this mathematical strand. As above, Numicon and multilink are extremely useful resources in supporting children in their calculation of perimeter word problems. 

These problems begin in Year 3 and will be based on one objective: measure the perimeter of simple 2-D shapes. The progression continues into Year 6 with problems being based on one objective: recognise that shapes with the same areas can have different perimeters and vice versa.

Perimeter word problem: Year 6 (crossover with decimals and multiplication)

  • Josh has drawn a square. Each side is 7.5cm. What is the perimeter of the square? Answer: 30cm

Ratio word problems 

In my experience, ratio is most successful when taught with concrete resources such as multilink, Cuisenaire rods or beads. Once children are taught how to represent ratio word problems using equipment (and eventually transferring to a pictorial representation, such as a bar model), the process is a lot easier.

Children won’t encounter ratio word problems until Year 6, where they will be based on three objectives:

  • solve problems involving the relative sizes of two quantities where missing values can be found by using integer multiplication and division facts
  • solve problems involving similar shapes where the scale factor is known or can be found
  • solve problems involving unequal sharing and grouping using knowledge of fractions and multiples

Ratio word problem: Year 6 (crossover with measurement)

  • A local council has spent the day painting double yellow lines. They use 1 pot of yellow paint for every 100m of road they paint. How many pots of paint will they need to paint a 2km stretch of road? Answer: 20 pots

Order of operations word problems

Children won’t encounter word problems about the order of operations until Year 6, where they will be based on one objective: use knowledge of the order of operations to carry out calculations involving the four operations. The non-statutory guidance in the National Curriculum also recommends that children explore the order of operations using brackets (otherwise known as BODMAS or BIDMAS); for example, 2 + 1 x 3 = 5 and (2 + 1) x 3 = 9.

Bodmas word problem: Year 6

  • Draw a pair of brackets in one of these calculations so that they make two different answers. What are the answers?
  • 50 – 10 × 5 =
  • 50 – 10 × 5 =

Volume word problems 

Children won’t encounter volume-related word problems until Year 6, where they will be based on two objectives:

  • recognise when it is possible to use formulae for area and volume of shapes
  • calculate, estimate and compare volume of cubes and cuboids using standard units, including cubic centimetres and cubic metres, and extending to other units

Volume word problem: Year 6

This large cuboid has been made by stacking shipping containers on a boat. Each individual shipping container has a length of 6m, a width of 4m and a height of 3m. What is the volume of the large cuboid? Answer: 864m3

Algebra word problems

Again algebra word problems only really come up in Year 6; the objectives they will be based on are: 

  • use simple formulae
  • generate and describe linear number sequences
  • express missing number problems algebraically
  • find pairs of numbers that satisfy an equation with 2 unknowns
  • enumerate possibilities of combinations of 2 variables

Algebra word problem: Year 6

This question is from the 2018 KS2 SATs paper. It is worth 2 marks as there are 2 parts to the answer.

Amina is making designs with two different shapes. She gives each shape a value. Calculate the value of each shape.

Word problems on division for fourth grade students are solved here step by step.

Consider the following examples on word problems involving division:

1. $5,876 are distributed equally among 26 men. How much money will each person get?

Solution:

Money received by 26 men = 5876 So, money received by one man = 5876 ÷ 26

= 226

Word Problem on Division

Each man will get $226. 

2. If 9975 kg of wheat is packed in 95 bags, how much wheat will each bag contain?

Solution:

Since 95 bags contain wheat 9975 kg

Therefore, 1 bag contains wheat (9975 ÷ 95) kg

= 105 kg

Division Word Problem

Each bag contains wheat = 105 kg

In a problem sum involving division, we have to be careful about using the remainder.

3. 89
people have been invited to a banquet. The caterer is arranging tables.
Each table can seat 12 people. How many tables are needed?

Solution:

To answer this question, we need to divide 89 by 12
89 ÷ 12

Division Word Problems

Quotient — 7 

Remainder — 5

If the caterer arranges 7 tables, then 5 people will have no place to sit. 
So he needs to arrange 7 + 1 = 8 tables. 

4. How many hours are there in 1200 minutes? 

Solution:

We know that there are 60 minutes in 1 hour.Divide the number of minutes by the number of minutes in 1 hour. We get, divide 1200 by 601200 ÷ 60 = 20

So there are 20 hours in 1200 minutes.

Answer: 20 hours. 

5. A bus can hold 108 passengers. If there are 12 rows of seats on the bus, how many seats are in each row? 

Solution:

Total number of passengers = 108

There are 12 rows of seats on the bus.

To find how many seats are there in each row, divide the total number of passengers by the number of rows of seats on the bus.

We get, divide 108 by 12

108 ÷ 12 = 9

Therefore, there are 9 seats in each row.

Answer: 9 seats.

6. Tom had 63 apples. He divides all apples evenly among 9 friends. How many apples did Tom give to each of his friends?

Solution:

Total number of apples = 63

There are 9 friends of seats on the bus.

To find how many apples Tom gave to each of his friends, divide the total number of apples by the number of friends. 

We get, divide 63 by 9

63 ÷ 9 = 7

Therefore, Tom gives 7 apples to each of his friends.

Answer: 7 Apples

7. Mark baked 195 cookies and divided them equally into 13 packs. How many cookies did Mark put in each packet?

Solution:

Total number of cookies = 195

There are 13 packs.

To find how many cookies did Mark put in each packet, divide the total number of cookies by the number of packs.

We get, divide 195 by 13

195 ÷ 13 = 15

Therefore, Mark put 15 cookies in each pack.

Answer: 15 cookies.

9.
Nancy needs 5 lemons to make a glass of orange juice. If Nancy has 250
oranges, how many glasses of orange juice can she make?

Solution:

Total number of oranges = 250

She needs 5 lemons to make a glass of orange juice.

To
find how many glasses of orange juice can Nancy make, divide the total
number of oranges by the number of oranges needed for each glass of
orange juice.

We get, divide 250 by 5

250 ÷ 5 = 50

Therefore, Nancy can make 50 glasses of orange juice.

Answer: 50 glasses of orange juice.

10. In your classes you counted 120 hands. How many students were at the class?

Solution:

Total number of hands = 120

We have 2 hands.

To find how many students were at the class, divide the total number of hands by the number of hands we have.

We get, divide 120 by 2

220 ÷ 2 = 60

Therefore, there were 60 students at the class.

Answer: 60 students.

11. The total train fare for 20 persons is 7540 rupees. What is the fare for 1 person.

If you looking for different questions on Sets you have come the right way. We have curated Word Problems on Sets with Step by Step Solutions for your understanding. Make use of them while practicing Sets Problems and increase your conceptual knowledge. In this, you will understand how to Solve Sets Word Problems using Venn Diagrams easily. If you need help on different concepts of Sets refer to Set Theory and learn the representation of a set, types of sets, etc. Check out the Solved Examples provided and learn how to solve related problems during your work.

1.  Let A and B be two finite sets such that n(A) = 30, n(B) = 18 and n(A ∪ B) = 26, find n(A ∩ B)?

Solution:

Formula for n(A ∪ B) = n(A) + n(B) – n(A ∩ B).

Rearranging it we get the n(A ∩ B) = n(A) + n(B) – n(A ∪ B)

=30+18 – 26

= 22

Therefore, n(A ∩ B) = 22.

2. If If n(A – B) = 12, n(A ∪ B) = 45 and n(A ∩ B) = 15, then find n(B)?

Solution:

n(A∪B) = n(A – B) + n(A ∩ B) + n(B – A)

45 = 12+15 +n(B-A)

n(B-A) = 45-12-15

= 45-27

= 18

n(B) = n(A ∩ B) + n(B – A)

= 15+18

= 33

3. In a group of 80 people, 37 like cold drinks and 52 like hot drinks and each person likes at least one of the two drinks. Find How many people like both coffee and tea?

Solution:

Let A = Set of people who like cold drinks.

B = Set of people who like hot drinks.

Given

(A ∪ B) = 80 n(A) = 37 n(B) = 22 then;

n(A ∩ B) = n(A) + n(B) – n(A ∪ B)

= 37+52-80

= 89 – 80

= 9

Therefore, 9 people like both tea and coffee.

4. Let S={4, 5, 6}. Write all the possible partitions of S?

Solution:

Remember that partition of S is a collection of nonempty sets that are disjoint and their union is S.

Possible Partitions of S are

{4},{5},{6}
{4,5},{6}
{4,6},{5}
{5,6},{4}
{4,5,6}.

5. In a school, there are 30 teachers who teach Mathematics or Physics. Of these, 18 teach Mathematics and 6 teach both Physics and Mathematics. How many teach Physics only?

Solution:

Total Number of Teachers who teach Mathematics or Physics = 30

Number of Teachers who teach Mathematics n(M) = 18

Number of Teachers who teach both Mathematics and Physics n( M ∩ P) = 6

n(M) = 18 n( M ∩ P) = 6 and n (M ∪ P )= 30

n (M ∪ P ) = n(M) + n(P) – n(M ∩ P)

30 = 18 + n(P) – 6

30 = 12 + n(P)

⇒ n(P) = 30 – 12

⇒ n(P) = 18

Number of teachers teach Physics only = n( P – M)

n( P – M) = n(P) – n( M ∩ P )

= 18 – 6

n( P – M) = 12

Number of teachers who teach physics only is 12.

6. In a survey of 80 people, it was found that 35 people read newspaper H, 20 read newspaper T, 15 read the newspaper I, 5 read both H and I, 10 read both H and T, 7 read both T and I, 4 read all three newspapers. Find the number of people who read at least one of the newspapers?

Solution:

n(H) is the Number of People who read the newspaper H i.e. 35

n(I) is the Number of People who read the newspaper I i.e. 15

n(T) is the Number of People who read the newspaper T i.e. 20

n(H ∩ I) is the Number of People who read H and I i.e. 5

n(H ∩ T) is the Number of People who read H and T i.e 10

n(T ∩ I) is the Number of People who read T and I i.e. 7

n(H ∩ T ∩ I) is the Number of People who read all three Newspapers H, T, I i.e. 4

n(H ∪T ∪ I ) is the Number of people who read at least one of the newspapers

n(H ∪T ∪ I ) = n(H) + n(T) + n(I) – n(H ∩ T) – n(T ∩ I) – n(H ∩ I) + n(H ∩ T ∩ I)

n(H ∪T ∪ I )= 35+20+15-10-7-5+4

= 74-22

= 52

Therefore, the number of people who read at least one of the newspapers is 52.

7.  In a school, all pupils play either Hockey or Football or both. 400 play Football, 150 play Hockey, and 130 play both the games. Find
(i) The number of pupils who play Football only,
(ii) The number of pupils who play Hockey only,
(iii) The total number of pupils in the school.

H = Hockey and F = Football

n (H ) = 150 n (F)= 400

n ( H ∩ F) = 130

(i) The number of pupils who only play Football = n (F – H )

n (F – H ) = n(F) – n( F ∩ H )

= 400 – 130

= 270

(ii) The number of pupils who only play Hockey = n (H – F )

n (H– F ) = n(H) – n( F ∩ H )

= 150 – 130

= 20

(iii) The total number of pupils in school

= n(H) + n(F) – n (F ∩ H)

= 150 + 400 – 130

= 420
