GMAC GMAC Data Insights 2 — Questions and Answers
Question 1: In a GMAC graphics interpretation question, a pie chart shows that 35% of costs are labor. If total costs are $200,000, how much is spent on labor?
- $60,000
- $70,000 (Correct answer)
- $75,000
- $65,000
Correct answer: $70,000
35% of $200,000 = 0.35 × $200,000 = $70,000.
Question 2: A two-part analysis asks you to determine if a dataset's median is less than its mean. Given values 2, 3, 3, 4, 18, what is the median?
- 2
- 3 (Correct answer)
- 4
- 18
Correct answer: 3
When the five values are sorted (2,3,3,4,18), the middle (third) value is 3, which is the median.
Question 3: A GMAC Data Insights question shows a bar chart where sales increased by 10% each year for 3 years starting at $100K. What are sales in year 3?
- $121,000
- $130,000
- $133,100 (Correct answer)
- $110,000
Correct answer: $133,100
Year 1: $110K, Year 2: $121K, Year 3: $133,100 after compounding 10% annually three times.
Question 4: In a table analysis, you sort by 'profit margin' descending. Company X has revenue $500K and costs $425K. What is its profit margin?
- 15% (Correct answer)
- 17%
- 14%
- 16%
Correct answer: 15%
Profit = $500K − $425K = $75K; margin = $75K/$500K = 15%.
Question 5: A multi-source reasoning passage states a project is 60% complete after 9 months. At this rate, how many total months will the project take?
- 12 months
- 14 months
- 15 months (Correct answer)
- 18 months
Correct answer: 15 months
If 60% takes 9 months, then 100% takes 9/0.60 = 15 months.
Question 6: A GMAC Data Insights scatter plot shows a strong positive correlation between advertising spend and sales. Which conclusion is best supported?
- Higher ad spend causes higher sales
- Higher ad spend is associated with higher sales (Correct answer)
- Lower sales cause lower ad spend
- The data proves a causal relationship
Correct answer: Higher ad spend is associated with higher sales
Correlation shown in a scatter plot indicates association, not causation.
