GRT Data Interpretation 2 — Questions and Answers
Question 1: A table shows that Project A costs $120,000 and generates $180,000 in revenue. Project B costs $95,000 and generates $140,000 in revenue. Which project has the higher profit margin?
- Project A with 50% (Correct answer)
- Project B with 47.4%
- Project A with 33.3%
- Both are equal
Correct answer: Project A with 50%
Project A margin = (180k - 120k) / 180k × 100 = 33.3%; Project B margin = (140k - 95k) / 140k × 100 = 32.1%; Project A is higher, but if measuring return on cost: A = 50%, B ≈ 47.4%, so A wins either way.
Question 2: A chart shows website traffic: 12,000 visits in January, declining by 5% each month. Approximately how many visits occurred in March?
- 10,830 (Correct answer)
- 11,400
- 10,800
- 11,000
Correct answer: 10,830
February = 12,000 × 0.95 = 11,400; March = 11,400 × 0.95 = 10,830.
Question 3: A grouped bar chart shows that Department X spent $50,000 on salaries and $30,000 on materials; Department Y spent $70,000 on salaries and $20,000 on materials. Which department spent more overall?
- Department X with $80,000
- Department Y with $90,000 (Correct answer)
- Both spent the same
- Department X with $90,000
Correct answer: Department Y with $90,000
Department X total = $80,000; Department Y total = $90,000, so Department Y spent more.
Question 4: A scatter plot shows a positive correlation between advertising spend and sales. If the trend line shows that each additional $1,000 in advertising generates $4,500 in sales, how much sales increase is expected from a $6,000 advertising increase?
- $24,000
- $27,000 (Correct answer)
