Numerical Reasoning Data Interpretation 2 — Questions and Answers
Question 1: A table shows employee headcount by region: North=320, South=280, East=410, West=190. What percentage of total employees work in the East?
- 34.2% (Correct answer)
- 28.0%
- 41.0%
- 32.8%
Correct answer: 34.2%
Total = 320+280+410+190 = 1,200; East % = 410/1,200 × 100 ≈ 34.2%.
Question 2: A chart shows monthly expenses: Rent=$1,200, Food=$450, Transport=$300, Utilities=$150, Other=$200. What fraction of total expenses is spent on food?
- 1/5
- 3/16
- 9/46 (Correct answer)
- 2/9
Correct answer: 9/46
Total = 1200+450+300+150+200 = 2,300; Food fraction = 450/2,300 = 9/46.
Question 3: A table shows project completion rates: Project A=75%, B=90%, C=60%, D=85%, E=70%. What is the mean completion rate?
- 76% (Correct answer)
- 80%
- 72%
- 78%
Correct answer: 76%
Mean = (75+90+60+85+70)/5 = 380/5 = 76%.
Question 4: A bar chart shows items sold: Product X=450, Y=380, Z=520, W=290. What is the ratio of Product Z sales to Product W sales (in simplest form)?
- 52:29 (Correct answer)
- 26:14.5
- 18:10
- 16:9
Correct answer: 52:29
Z:W = 520:290 = 52:29 (divide both by 10; GCD of 52 and 29 is 1, so 52:29 is simplest).
Question 5: A table shows profit margins over 3 years: Year1=12%, Year2=15%, Year3=9%. If Year1 revenue was $500,000, Year2=$600,000, Year3=$550,000, which year had the highest absolute profit?
- Year2 (Correct answer)
- Year1
- Year3
- All equal
Correct answer: Year2
Year1 profit=0.12×500K=$60K; Year2=0.15×600K=$90K; Year3=0.09×550K=$49.5K; Year2 is highest.
Question 6: A pie chart shows market share: Brand A=35%, B=25%, C=20%, D=12%, E=8%. If total market value is $4.8 billion, how much more does Brand A hold than Brand E (in $ billions)?
- $1.30B (Correct answer)
- $1.25B
- $1.44B
- $1.10B
Correct answer: $1.30B
A = 0.35×4.8 = $1.68B; E = 0.08×4.8 = $0.384B; difference = 1.68−0.384 = $1.296B ≈ $1.30B.
