Why Practice GRE Data Interpretation Questions?

GRE Data Interpretation questions assess your ability to understand, visualize, and use the information effectively. These skills are also important for being a data analyst and can be required at any stage of your career. Also, it is a crucial part of the Quant section on the GRE as 3-4 questions are expected in each section of the GRE maths.
Data Interpretation in the GRE doesn’t require an understanding of complex math concepts. You need to focus on some basic concepts like percentages, averages, and basic mathematical concepts. For example, figures/graphs/charts, allow you to understand the information given in the question without making any effort to read a long passage. Graphs help you learn a lot of information in a shorter amount of time, but the chances of error also increase.

If you are looking to achieve a score of 160+ in the Quant section, then it is important to spend enough time to learn and practice Data Interpretation questions.

Understanding Data Interpretation Questions on the GRE

These types of questions on the GRE are meant to analyze data. To understand this effectively and efficiently, you need to know the types of graphs used to represent the data.

Types of GRE Data Interpretation Formats and Questions

Several types of graphs, tables, or charts represent the data. On the GRE, data interpretation questions are asked in various forms. You need to learn different forms of data representation so that you can familiarize yourself with these.

Let us discuss them one by one.

GRE Data Interpretation Table Questions

In tables, the data is given in an organized form but not represented visually. You should analyze the data to see any trend in the values.

Example:

The following two questions are based on the table below, which is a record of the number of employees in the different departments of an organization.

Question: What is the average age of the employees in the HR and Training department together?

(A) 26
(B) 27
(C) 27.5
(D) 28
(E) 29

Solution:

The average age of the employees in the HR and Training department together = 29×8+26×816=27.5 years

Hence, the correct answer is option C.

GRE Data Interpretation Graph Questions

The common graphs asked in the GRE are Bar graphs, line graphs, and Histograms.

Bar Graphs: Data represented in the form of rectangular vertical or horizontal bars where one parameter is given on the x-axis and the other parameter is given on the y-axis is called a bar graph.

The height of the bar is proportional to the value of the parameter.

Example:

The following question is based on the bar graph below, which shows the results of a survey about the favourite colour of children in a school.

Question: What percent of the students have black colour as their favourite?

(A) 10.2%
(B) 12.5%
(C) 25%
(D) 27%
(E) 29.3%

Solution:

Estimate the number of students in each bar, then add.
20 + 5 + 26 + 23 + 13 + 20 = 107

Students with black colour favourite = 13

Required percentage = 13107 ×100=12.15%

Hence, the correct answer is option B.

Line Graphs: A line graph shows the relationship between points over some time by a line or curve. Data is represented at the points of the line graph.

It is best for displaying continuous data or a sequence of values.

Example:

The following question is based on the line graphs below. The graph below shows a company’s earnings for each month between April and August.

Question: By what percentage has the company’s earnings increased from April to August?

(A) 50%
(B) 65%
(C) 75%
(D) 100%
(E) 150%

Solution:

Company’s earnings in April = $2 million

Company’s earnings in August = $3 million

Percentage increase in the earnings = 3-22×100=50%.

Hence, the correct answer is option A.

GRE Data Interpretation Charts Questions

The data interpretation questions asked are mainly based on pie charts. A pie chart is a circular chart divided into sectors; each sector represents the data for an entity.

These charts are divided either in terms of angles or percentages.

Pie Chart Example:

The various expenditures incurred by a renowned publishing company in the US for publishing books in 2023 are given below in a pie chart.

Question: If the expenditure on printing cost is $2000 more than the expenditure cost on royalty, find the expenditure on paper cost of the company.

(A) $2000(B)$4000
(C) $6000(D)$10000
(E) $12000

Solution:

Company’s expenditure on printing cost = 20%

Company’s expenditure on royalty = 15%

So, 20% - 15% = $2000

⇒ 5% = $2000

Now, the Company’s expenditure on paper cost = 25% = $5\times 2000=$10000

Hence, the correct answer is option D.

Questions on Scatter Plots

A scatter plot is generally used to represent data to examine two variables for a common set of subjects.

For example; a scatter graph can be used to represent the age and religious views of a group of people. Another example could be the relationship between the annual income and the number of kids in a group of people.

Example:

Refer to the following graph to answer the question followed

Question: What is the difference between the sales and net profit (in Rs. Lakhs) in 1978?

(A) 19.8

(B) 27.5

(C) 43.5

(D) 56.3

(E) 59.7

Solution:

Sales (in Rs. Lakhs) in 1978 = 61.5

Net Profit (in Rs. Lakhs) in 1978 = 5.2

Difference = 61.5 – 5.2 = 56.3

Hence, the correct answer is option D.

GRE Data Interpretation Passages with Data (Caselet) Questions

Information is given in the form of a paragraph. There is no visual representation of data. You need to read the passage carefully to fetch the key information.

These paragraphs are based on either reasoning or numeric data.

Example:

Directions: Study the given information carefully to answer the question followed.

Three friends Sam, Rads, and George spend 12%, 14%, and 16% of their monthly salary on travelling in the given order and each of them saves half of the remaining amount. The monthly salary of Sam and George is the same and the monthly saving of Sam is $36morethanthatofGeorge.ThetotalexpendituresofSamandRadstogetherontravellingis$124 more than that of George.

Question. What is the monthly income of Sam, Rads, and George altogether?

(A) $1400

(B) $1800

(C) $2200

(D) $3600

(E) $5000

Solution:

Let the monthly income of Sam = monthly income of George = $100x

Expenses of Sam on travelling = $12x

Expenses of George on travelling = $16x

Since each of them saves half of the remaining amount,

Savings of Sam = $(100x–12x)/2=$44x

Savings of George = $(100x–16x)/2=$42x

According to the question; 44x – 42x = 36

So, x = 18

So, monthly income of Sam = monthly income of George = $1800

Also, Expenses of Sam and George on travelling = $(12x+16x)=$504

Therefore, Expenses of Sam and Rads on travelling = $(12x+14$16x + 124
So, 14% of monthly income of Rads = 16x – 12x + 124 = 4x + 124 = $(72+124)=$196

So, monthly income of Rads = $1400

Monthly income of the three altogether = $(1800+1800+1400)=$5000

Hence, the correct answer is option E.

Other graphs can also be used to represent the data such as

• Double Bar graph

• Spider graph

• Combination of two or more charts.

Strategies for Tackling GRE Data Interpretation Questions

The information needed to solve the questions is given in the graphs. You need not take any value at your own. You just need to make proper strategies to solve these questions.

Particularly, you must have

• Read and analyze the details given in the question.

• Ability to interpret all the necessary information from the graphs, and avoid irrelevant information.

Here are some Data Interpretation GRE Tips and Tricks 2025 to ace the data interpretation questions in the GRE.
Tip 1: Analyzing the Data Efficiently

When the DI questions pop up in front of you, the first thing you should do is to have a look at the image in the question and understand the data provided in the image.

Few things you need to do:

• Read the graph properly.

• Interpret the values accurately.

• Understand the concept required to solve the associated questions.

• If any value is missing, find that value first.

Tip 2: Identifying Key Information Quickly

After analyzing the data, the next thing you should do is look for key information. Read the question statement carefully and understand what is asked in the question.

Sometimes excess information is given in the question, you need to avoid the excess information and identify the appropriate information required to answer the question.

DI section tests your focus and presence of mind. If you don’t read the question properly then you may end up choosing the wrong answer choice. This is because of time crunch and being overconfident.

Common things to focus

• Units of measurement in the axes

• Decimal points

• Correct Units

Tip 3: Common Mistakes to Avoid

There are plenty of mistakes, students often make while solving the data interpretation questions.

You should avoid such mistakes and a few of them are listed here:

1. The question should be solved only based on the information provided with the question itself. Do not use any information that is not given in the question.

2. Wasting too much time on a single question.

3. Generally, due to time crunch, students often don’t read the question properly. You should not do that.

4. Do not misinterpret the information. It happens because of impatience or overconfidence.

5. Sometimes, students get so involved in solving the question that they forget to look for time, and at last they suffer a lack of time. So, always have an eye on the clock.

6. Finding this section easy, students avoid practising this section. Do not do that. Practice more to master this section.

Tip 4: Time Management Tips

You need to solve the question within the given time. So, you need to manage the time during the exam. Here are some suggestions you may follow:

• To analyze the graph and identify the key information, you should spend about 30 to 40 seconds.

• You need to remember that you have about 2 minutes to solve a question. So, you have to do your calculations in 1 minute.

• To save time, don’t use too much formula approach. Think beyond the formulas. Spend only 15 to 30 seconds analyzing the graph and jotting down key information. Then, proceed with your calculations. Remember, you only have 2 minutes for each question.

• Since these questions usually take more time to solve as compared to other quant questions. You need to balance the time throughout the section.

Answers and Explanations

Answers:

Explanation:

1. The average earnings of the three companies from China = 180+200+2603=213.33 millions.

2. Estimate the value of earnings of Amazon from China and India and then find the required percentage.

Earnings of Amazon from China = 200 million

Earnings of Amazon from India = 120 million

Required percentage = = 200-120200×100%=40%.

3. Estimate the earnings of Microsoft across the countries and add them.

Total earnings of Microsoft across the countries (in millions) = 340 + 460 + 180 + 240 = 1220.

4. Estimate the earnings of Amazon from the USA and Malaysia and the total earnings of Facebook from all four countries.

The earnings of Amazon from the USA and Malaysia (in millions) = 400 + 420 = 820.

Total earnings of Facebook from all four countries (in millions) = 160 + 120 + 260 + 360 = 900.

Required difference = 900 – 820 = 80.

5. Estimate the revenue in 1989 and 1995 and then compare them.

Revenue in 1989 = 120

Revenue in 1995 = 220

Percentage increase in the revenue = 100220×100=45.45%

6. Estimate the expenditure from 1991 to 1994 and then add them to find the average.

Sum of the expenditure from 1991 to 1994 = 115 + 125 + 135 + 140

Average = (115 + 125 + 135 + 140)/ 4 = 128.75

7. Estimate the expenditure from 1990 and 1995.

The expenditure in 1990 = 110

The expenditure in 1995 = 150

The required percentage = 110150×100=73.33%

8. Estimate the profits from 1989 to 1991.

Estimate the profits from 1993 to 1995.

Profits from 1989 to 1991 = 20 + 25 + 30 = 75

Profits from 1993 to 1995 = 50 + 60 + 70 = 190

The required percentage = 11575×100=153.33%

D. 81

E. 90

Answers and Explanations

Answers:

Explanation:

1. Estimate the expenses using the given information.

8% of expenses = $200

So, expenses on rent and education together = 35% = 2008×35=$875.

2. Estimate the value of 1% of monthly income of Maria.

Maria’s expenses on food = 22% = $220

So, 22% of the monthly income of Maria = $220

So, the monthly income of Maria = $1000

3. Expenses on ‘Others’ = 35% = $700

Difference between the expenses on Transport and Food = 22% - 8% = 14% = 70035×14=$280

4. Here, 100% = 360o

Expenses on rent, food, and education put together = 15% + 22% + 20% = 57%

An angle formed by rent, food, and education put together = 57100×360 = 205.2o

5. Export of company A in 2000: Import of company A in 2000 = 1.75 = 7/4

Assume that Export = 7x and Import = 4x

So, the difference between Imports and Exports = 3x = $30000

So, the value of Import = 4x = 300003×4=$40000.

6. Export of company D in 2002: Import of company D in 2002 = 0.75 = 3/4

Assume that the Export of Company D = 3 and import of Company D = 4

Now, Export of company E in 2002: Import of company E in 2002 = 1

Assume that the Export of Company E = 4 and the import of Company E = 4 (Since the import of Company D and E are the same)

So, required percentage = 4-33×100=33.33%

7.

Total Import = $22000+$19200 + $27000=$68200

8. For company C, Export to import is 1.75 = 7: 4

For company D, Export to import is 1 1 = 1: 1 = 4: 4

So, required percentage = 7-44×100=75%

(A) 50

(B) 58

(C) 62

(D) 72

(E) 82

Answers and Explanations:

Answers:

Explanation:

1. From the information given, we can deduce that

Sales

D = A/2

C = $12 million = B/4

So, B = $48 million

D = C + $10million=$22 million

A = 2D = $44 million

A + B + C + D = 44 + 48 + 12 + 22 = $126 million

2. Sales of company A = $44 million

Expenses of company A = 80% of $44million=$35.2 million

Profit of company A = 44 – 35.2 = $8.8 million

Profit of company D = A/2 = $4.4 million

Expenses of D = 22 – 4.4 = $17.6 million

Expenses of C = 17.6 – 2 = $15.6 million

A – C = 35.2 – 15.6 = $19.6 million

3. Sale of company A = $44 million

Expenses of company A = $35.3 million

Profit of company A = 44 – 35.2 = $8.8 million

4. Profit of company A = 44 – 35.2 = $8.8 million

Sale of company B = $48 million

Expenses of C = 17.6 – 2 = $15.6 million

Profit of company C = 12 – 15.6 = - $3.6 million

Profit of company B = -3.6 – 1 = - $4.6 million

Expenses of company B = 48 – (-4.6) = $52.6 million

So, required difference = 52.6 – 8.8 = $43.8 million

5. Average units sold by B, D, and F together = (300 + 440 + 400)/3 = 380

6. Required percentage = 850-700700×100%=21.42%

7. Average number of Units produced by all companies = (900 + 700 + 300 + 850 + 550 + 600)/6 = 650.

Required difference = 900 – 650 = 250

8. Total units produced = 900 + 700 + 300 + 850 + 550 + 600 = 3900

Total Units Sold = 650 + 300 + 150 + 450 + 300 + 400 = 2250

Required percent = 22503900×100%=57.69%

Tips for Using GRE Data Interpretation Practice Papers 2025 Effectively

Using practice sets effectively is an art. You must be the master of that art. There are a few important points to remember while using practice sets such as

• Create an exam-like environment at your home

• Learn from your mistakes

• Give proper time to practice sets and include them in your study plan.

Let us discuss these in detail.

How to Simulate Test Conditions:

You are recommended to create an environment just like the exam environment that you might get on the day of the exam. This can help you to get in the right mindset.

What you should do:

• Choose the right space to take your practice sets where you get proper light and the place needs to be quiet.

• Ensure that there is no distraction or minimum distraction or noise.

• Keep a water bottle with you.

• Check your internet connectivity before taking the test.

• Ensure to finish the exam in a single go.

Also, you can incorporate this into your practice sessions.

Reviewing and Analyzing Mistakes

Reviewing and analyzing your mistakes will help you to grow up as an individual. It will help you to understand the common errors that you should not make during exams.

There are three steps to follow:

Review first: You should acknowledge your mistakes and make an error log to make a record of common errors that you are making.

Analyze: Analyze the errors and mistakes. Understand what types of errors you are making, understand why the silly mistakes are happening, and what you need to do to rectify them.

Categorize your errors in:

• Conceptual errors

• Calculation Errors

• Silly Mistakes

Learn from the mistakes: The most important part is learning from the mistakes. Update your error log after each test and check the trend of the error. For good preparation, this trend should be decreasing. After each test, the number of mistakes should be decreasing.

This practice will help you to understand the weaker portion and general errors that you are making. Practice more in these areas.

Incorporating Practice into Your Study Plan

You are suggested to create a study plan in which you should incorporate the practice tests at a regular duration. Also, you should allocate some time to review and analyze your tests and test scores. A good study plan is flexible and can be changed as per requirement.
