Korn Ferry Assessment Numerical Reasoning 4 — Questions and Answers
Question 1: A table shows three products with unit costs of $12, $18, and $25, and units sold of 500, 300, and 200 respectively. What is the total revenue?
- $15,400
- $16,400 (Correct answer)
- $17,400
- $18,400
Correct answer: $16,400
Revenue: (500×$12) + (300×$18) + (200×$25) = $6,000 + $5,400 + $5,000 = $16,400.
Question 2: Staff headcount rose from 240 to 288 over two years. What was the average annual percentage increase?
- 8%
- 10% (Correct answer)
- 15%
- 20%
Correct answer: 10%
Total increase = 20%; average per year ≈ 10% (since (1.10)² ≈ 1.21, closest to 20% total).
Question 3: A ratio of managers to staff is 1:8. If there are 360 staff members, how many managers are there?
- 40
- 45 (Correct answer)
- 48
- 50
Correct answer: 45
360 ÷ 8 = 45 managers.
Question 4: A line chart shows website visits: Jan=12,000, Feb=15,600, Mar=14,040. What was the percentage change from Feb to Mar?
- -10% (Correct answer)
- -8%
- -5%
- -12%
Correct answer: -10%
(14,040 − 15,600) ÷ 15,600 × 100 = −1,560 ÷ 15,600 × 100 = −10%.
Question 5: An employee earns a base salary of $52,000 plus a 7% commission on all sales above $100,000. If they make $250,000 in sales, what is their total compensation?
- $60,500
- $62,500
- $64,500 (Correct answer)
- $66,500
Correct answer: $64,500
Commission = 7% × ($250,000 − $100,000) = 7% × $150,000 = $10,500; total = $52,000 + $10,500 = $62,500.
Question 6: Three departments share a budget of $900,000 in the ratio 4:3:2. How much does the largest department receive?
- $300,000
- $350,000
- $400,000 (Correct answer)
- $450,000
Correct answer: $400,000
Total parts = 9; largest share = (4/9) × $900,000 = $400,000.
Question 7: If it takes 4 machines 6 hours to produce 1,200 units, how many hours would 8 machines take to produce 3,600 units?
- 7
- 8
- 9 (Correct answer)
- 10
Correct answer: 9
Rate per machine = 1,200 ÷ (4×6) = 50 units/hr; 8 machines = 400 units/hr; 3,600 ÷ 400 = 9 hours.
