GMAT Data Insights: Integrated Reasoning Mixed Practice 2 — Questions and Answers
Question 1: In a Multi-Source Reasoning set, a memo states shipping costs rose 12% while a table shows costs went from $50 to $60 per unit. Are the two sources consistent?
- Yes, both indicate a 12% rise
- No, the table shows a 20% rise (Correct answer)
- No, the table shows a 10% rise
- Cannot be determined
Correct answer: No, the table shows a 20% rise
Going from $50 to $60 is a $10 increase, which is 20%, contradicting the memo's 12%.
Question 2: A Two-Part Analysis asks you to pick one value for 'price that maximizes revenue' and another for 'price that maximizes units sold.' These selections should be made in which columns?
- The same single column for both
- Two separate columns, one per requirement (Correct answer)
- Any column, order does not matter
- Only the rightmost column
Correct answer: Two separate columns, one per requirement
Two-Part Analysis requires one answer in each of the two distinct columns for the two separate conditions.
Question 3: A Graphics Interpretation scatterplot shows a strong negative correlation between advertising spend and unsold inventory. This suggests that as advertising increases, unsold inventory tends to:
- Increase
- Decrease (Correct answer)
- Stay constant
- Become more variable
Correct answer: Decrease
A negative correlation means the two variables move in opposite directions, so more advertising aligns with less unsold inventory.
Question 4: In a Table Analysis task, you sort a dataset by 'profit margin' descending. The top row shows the company with the:
- Lowest profit margin
- Highest profit margin (Correct answer)
- Median profit margin
- Highest revenue
Correct answer: Highest profit margin
Descending sort places the largest value first, so the top row has the highest profit margin.
Question 5: A question gives that 30% of 400 survey respondents preferred Product A. How many respondents is that?
- 90
- 120 (Correct answer)
- 130
- 150
Correct answer: 120
30% of 400 equals 0.30 × 400 = 120.
Question 6: In Multi-Source Reasoning, an email says 'all qualified candidates passed the interview' and a list shows Candidate X passed but was unqualified. What can you conclude?
- The email is contradicted
- X must be qualified
- The email remains fully consistent (Correct answer)
- X failed the interview
Correct answer: The email remains fully consistent
The email only claims qualified candidates passed; it says nothing about unqualified ones, so X passing does not contradict it.
Question 7: A Graphics Interpretation bar chart shows quarterly sales of 200, 250, 300, and 350 units. The average quarterly sales is:
- 275 (Correct answer)
- 300
- 250
- 290
Correct answer: 275
The sum is 1,100 and dividing by 4 quarters gives 275.
