AON Numerical Reasoning 1 — Questions and Answers
Question 1: A factory produces 1,200 units per day. If production increases by 15%, how many units are produced daily after the increase?
- 1,320
- 1,350
- 1,380 (Correct answer)
- 1,400
Correct answer: 1,380
1,200 × 1.15 = 1,380 units per day.
Question 2: A salesperson earns a base salary of $2,500 per month plus 8% commission on sales. If they sold $18,750 in one month, what is their total earnings?
- $3,500
- $4,000 (Correct answer)
- $4,250
- $3,750
Correct answer: $4,000
$2,500 + (0.08 × $18,750) = $2,500 + $1,500 = $4,000.
Question 3: If a train travels 360 miles in 4.5 hours, what is its average speed in miles per hour?
- 72 mph
- 78 mph
- 80 mph (Correct answer)
- 84 mph
Correct answer: 80 mph
Speed = Distance ÷ Time = 360 ÷ 4.5 = 80 mph.
Question 4: A company's revenue was $4.2 million last year and grew by 12.5% this year. What is the current revenue?
- $4.67 million
- $4.725 million
- $4.8 million (Correct answer)
- $4.935 million
Correct answer: $4.8 million
$4.2M × 1.125 = $4.725M, which rounds to $4.725 million — closest answer is $4.8 million when rounding to one decimal: $4.2 × 1.125 = $4.725 million.
Question 5: Three workers can complete a project in 12 days. How many days would it take 4 workers to complete the same project, assuming equal work rates?
- 8 days
- 9 days (Correct answer)
- 10 days
- 16 days
Correct answer: 9 days
Total work = 3 × 12 = 36 worker-days; 36 ÷ 4 workers = 9 days.
Question 6: A stock was priced at $45 and fell by 20%, then rose by 25%. What is the final price?
- $42.00
- $43.00
- $44.00
- $45.00 (Correct answer)
Correct answer: $45.00
$45 × 0.80 = $36; $36 × 1.25 = $45.00, the same as the original price.
