What To Expect From The GMAT Data Insights Section [Practice Questions]

GMAC introduced a whole new section called Data Insights with the GMAT Focus Edition. Right now, no one knows the details about the types of questions and concepts on the test starting this October. Since Data Sufficiency is removed from the Quant section and the IR section is missing from the new exam, we have a hunch! In this blog, we are speculating on the kind of questions you can expect in the brand-new Data Insights section. Let’s go!

GMAT Data Insight Practice Questions [Difficulty Level: Moderate]

GMAT Data Insight Practice Question 1:

A company conducted a survey to analyze the preferences of its customers. The survey included questions about three product categories: Electronics, Clothing, and Home Appliances. Each respondent was asked to rank the three categories based on their preference, with 1 being the most preferred and 3 being the least preferred. The table below shows the preferences of five randomly selected respondents:

Based on the preferences of these respondents, which of the following statements is true?

1.  Respondent 2 prefers Electronics more than Home Appliances.
2.  Respondent 4 prefers Home Appliances more than Clothing.
3.  Respondent 1 prefers Home Appliances more than Electronics.
4.  Respondent 3 prefers Electronics more than Clothing.

Solution: To determine the correct statement, we need to compare the rankings given by each respondent. Let’s analyze each option:

A) Respondent 2 prefers Electronics more than Home Appliances.
Looking at the rankings given by Respondent 2, Electronics is ranked 2nd and Home Appliances is ranked 1st. This statement is false since Respondent 2 prefers Home Appliances more than Electronics.

B) Respondent 4 prefers Home Appliances more than Clothing.
Examining the rankings provided by Respondent 4, Home Appliances is ranked 2nd, while Clothing is ranked 3rd. This statement is true.

C) Respondent 1 prefers Home Appliances more than Electronics.
Analyzing the rankings given by Respondent 1, Home Appliances is ranked 3rd, and Electronics is ranked 1st. This statement is false since Respondent 1 prefers Electronics more than Home Appliances.

D) Respondent 3 prefers Electronics more than Clothing.
Looking at the rankings provided by Respondent 3, Electronics is ranked 1st, and Clothing is ranked 2nd. This statement is true.

Therefore, the correct statements are B) Respondent 4 prefers Home Appliances more than Clothing and D) Respondent 3 prefers Electronics more than Clothing.

GMAT Data Insight Practice Question 2:

Is the positive integer n divisible by 6?

Statement 1: n is divisible by both 2 and 3.
Statement 2: n is divisible by 4.

Solution: To determine if n is divisible by 6, we need to check if it is divisible by both 2 and 3. Let’s analyze each statement:

Statement 1: n is divisible by both 2 and 3.
This statement alone is not sufficient to determine if n is divisible by 6. For example, if n is 6, then it is divisible by both 2 and 3. However, if n is 2 or 3, it is not divisible by 6. Therefore, statement 1 is insufficient.

Statement 2: n is divisible by 4.
This statement alone is also not sufficient to determine if n is divisible by 6. For example, if n is 12, it is divisible by 4 and 6. However, if n is 4 or 8, it is divisible by 4 but not by 6. Therefore, statement 2 is insufficient.

Combining both statements:
By combining the statements, we know that n is divisible by 2, 3, and 4. Since 6 is the least common multiple of 2 and 3, if n is divisible by 4, it must also be divisible by 6. Therefore, combining the statements is sufficient to determine that n is divisible by 6.

The correct answer is (C) – Statements 1 and 2 together are sufficient to answer the question.

GMAT Data Insight Practice Question 3:

What is the value of the positive integer n?

Statement 1: n is a prime number greater than 5.
Statement 2: n^2 is a multiple of 5.

Solution: To determine the value of n, let’s analyze each statement:

Statement 1: n is a prime number greater than 5.
This statement alone is not sufficient to determine the value of n. There are multiple prime numbers greater than 5, such as 7, 11, 13, and so on. Therefore, statement 1 is insufficient.

Statement 2: n^2 is a multiple of 5.
If n^2 is a multiple of 5, then n must also be a multiple of 5. For example, if n = 5, then n^2 = 25, which is a multiple of 5. However, if n = 2, then n^2 = 4, which is not a multiple of 5. Therefore, statement 2 is insufficient.

Combining both statements:
By combining the statements, we know that n is a prime number greater than 5 and its square is a multiple of 5. The only prime number greater than 5 that satisfies this condition is n = 5 itself. Therefore, combining the statements is sufficient to determine that the value of n is 5.

The correct answer is (C) – Statements 1 and 2 together are sufficient to answer the question.

GMAT Data Insight Practice Questions [Difficulty Level: Moderate to High]

GMAT Data Insight Practice Question 4:

A company is analyzing the sales performance of its products over a five-year period. The table below shows the sales revenue (in millions) for three products (A, B, and C) in each of the five years:

Based on the table, what is the average sales revenue for Product B over the five-year period?

Solution: To calculate the average sales revenue for Product B, we need to sum up the sales revenue for Product B over the five years and divide it by 5. Let’s calculate:2016: $12 million

2017: $18 million
2018: $15 million
2019: $20 million
2020: $22 million

Total sales revenue for Product B = $12 million + $18 million + $15 million + $20 million + $22 million = $87 million

Average sales revenue for Product B = $87 million / 5 = $17.4 million

Therefore, the average sales revenue for Product B over the five-year period is $17.4 million.

GMAT Data Insight Practice Question 5:

A survey was conducted to analyze the preferences of customers for three car models (X, Y, and Z). The survey asked respondents to rate each car model on a scale of 1 to 10. The table below shows the average ratings given by the respondents:

Additionally, the survey provided the percentage of respondents who rated each car model as their top choice:

Car Model X: 30%
Car Model Y: 40%
Car Model Z: 30%

Based on the survey results, which car model has the highest overall preference?

Solution: To determine the car model with the highest overall preference, we need to consider both the average ratings and the percentage of respondents who rated each car model as their top choice. Let’s analyze:

Car Model X has an average rating of 7 and was rated as the top choice by 30% of the respondents.
Car Model Y has an average rating of 8 and was rated as the top choice by 40% of the respondents.
Car Model Z has an average rating of 6 and was rated as the top choice by 30% of the respondents.

Based on the average rating alone, Car Model Y has the highest rating. However, when considering the percentage of respondents who rated each car model as their top choice, Car Model Y also has the highest preference. Therefore, Car Model Y has the highest overall preference.

The correct answer is Car Model Y.

GMAT Data Insight Practice Question 6:

What is the value of the positive integer n?

Statement 1: n is a multiple of 9.
Statement 2: n is a multiple of 15.

Solution: To determine the value of n, let

Statement 1: n is a multiple of 9.

This statement alone is not sufficient to determine the value of n. There are multiple positive integers that are multiples of 9, such as 9, 18, 27, and so on. Therefore, statement 1 is insufficient.

Statement 2: n is a multiple of 15.
This statement alone is not sufficient to determine the value of n. There are multiple positive integers that are multiples of 15, such as 15, 30, 45, and so on. Therefore, statement 2 is insufficient.

Combining both statements:
By combining the statements, we know that n is a multiple of both 9 and 15. To find the value of n, we need to find the least common multiple (LCM) of 9 and 15. The LCM of 9 and 15 is 45. Therefore, combining the statements is sufficient to determine that the value of n is 45.

The correct answer is (C) – Statements 1 and 2 together are sufficient to answer the question.
