GMAT Data Insights: Integrated Reasoning Mixed Practice 3 — Questions and Answers
Question 1: A Two-Part Analysis presents an equation x + y = 20 and asks you to select a value of x and a value of y that satisfy it. If you choose x = 8, which y value works?
- 10
- 12 (Correct answer)
- 14
- 16
Correct answer: 12
If x = 8, then y must equal 20 − 8 = 12.
Question 2: In Table Analysis, a 'true/false' statement reads: 'More than half the 40 listed firms are profitable.' If 18 firms are profitable, the statement is:
- True
- False (Correct answer)
- Cannot be determined
- Exactly half
Correct answer: False
Half of 40 is 20, and 18 is fewer than 20, so the statement is false.
Question 3: A Graphics Interpretation line graph shows revenue rising steadily then flattening after year 3. The flattening indicates revenue growth that is:
- Accelerating
- Slowing or leveling off (Correct answer)
- Negative
- Exactly doubling
Correct answer: Slowing or leveling off
A flattening line means the rate of increase is slowing toward zero growth.
Question 4: Multi-Source Reasoning provides a price list and a discount memo offering 25% off items over $100. A $200 item would cost:
- $175
- $150 (Correct answer)
- $160
- $140
Correct answer: $150
25% of $200 is $50, so the discounted price is $200 − $50 = $150.
Question 5: In a Two-Part Analysis comparing two investments, you must mark which has the 'higher return' and which has the 'lower risk.' These could be:
- Always the same investment
- Always different investments
- The same or different investments (Correct answer)
- Impossible to mark separately
Correct answer: The same or different investments
The two criteria are independent, so one investment could satisfy both or each could satisfy a different one.
Question 6: A Table Analysis dataset of 5 cities has populations 1.2M, 0.8M, 2.0M, 1.5M, and 0.5M. The median population is:
- 0.8M
- 1.2M (Correct answer)
- 1.5M
- 2.0M
Correct answer: 1.2M
Sorted, the values are 0.5, 0.8, 1.2, 1.5, 2.0, and the middle value is 1.2M.
Question 7: A Graphics Interpretation dropdown asks you to complete: 'The region with the largest market share is ___.' You should base this on:
- The smallest plotted value
- The largest plotted value (Correct answer)
- The average value
- A randomly chosen value
Correct answer: The largest plotted value
Largest market share corresponds to the highest plotted data point.
