Ramsay Test Mathematical & Numerical Reasoning 3 — Questions and Answers
Question 1: A tank holds 480 liters and drains at 16 liters per minute. How long until empty?
- 30 minutes (Correct answer)
- 24 minutes
- 32 minutes
- 28 minutes
Correct answer: 30 minutes
480 ÷ 16 = 30 minutes.
Question 2: What is the average of 12, 18, 24, and 30?
- 21 (Correct answer)
- 20
- 22
- 24
Correct answer: 21
(12+18+24+30) ÷ 4 = 84 ÷ 4 = 21.
Question 3: A wire is 12 feet long and cut into 8-inch pieces. How many pieces result?
- 18 (Correct answer)
- 16
- 20
- 15
Correct answer: 18
12 ft = 144 in; 144 ÷ 8 = 18 pieces.
Question 4: Solve for x: 4x + 6 = 30.
- 6 (Correct answer)
- 9
- 8
- 5
Correct answer: 6
4x = 24, so x = 6.
Question 5: A motor runs at 1,800 RPM. How many revolutions in 90 seconds?
- 2,700 (Correct answer)
- 1,800
- 3,600
- 2,400
Correct answer: 2,700
1,800 RPM = 30 per second; 30 × 90 = 2,700.
Question 6: If 3 workers complete a job in 12 hours, how long for 6 workers at the same rate?
- 6 hours (Correct answer)
- 8 hours
- 4 hours
- 9 hours
Correct answer: 6 hours
Doubling workers halves the time: 12 ÷ 2 = 6 hours.
Question 7: What is 7/10 expressed as a percentage?
- 70% (Correct answer)
- 7%
- 0.7%
- 17%
Correct answer: 70%
7 ÷ 10 = 0.70 = 70%.
