ExxonMobil Test Numerical Reasoning 2 — Questions and Answers
Question 1: An ExxonMobil team completes a project in 24 days with 8 workers. How many days would the same project take with 12 workers?
- 16 days (Correct answer)
- 18 days
- 20 days
- 14 days
Correct answer: 16 days
(8 × 24) ÷ 12 = 192 ÷ 12 = 16 days.
Question 2: A chemical blend requires a ratio of 3 parts solvent to 5 parts base. How many liters of solvent are needed to produce 400 liters of the total blend?
- 150 liters (Correct answer)
- 120 liters
- 160 liters
- 180 liters
Correct answer: 150 liters
3 ÷ (3 + 5) × 400 = 3/8 × 400 = 150 liters.
Question 3: Fuel production at a plant increased from 18,000 to 22,500 tonnes per month. By what fraction did production increase?
- 1/4 (Correct answer)
- 1/3
- 1/5
- 1/6
Correct answer: 1/4
(22,500 − 18,000) ÷ 18,000 = 4,500 ÷ 18,000 = 1/4.
Question 4: A maintenance crew earns $45 per hour for regular time and $67.50 for overtime. In a week they work 40 regular hours and 8 overtime hours. What is total pay?
- $2,340 (Correct answer)
- $2,140
- $2,460
- $2,200
Correct answer: $2,340
(40 × $45) + (8 × $67.50) = $1,800 + $540 = $2,340.
Question 5: If a pump moves 360 gallons in 45 minutes, how long will it take the same pump to move 480 gallons?
- 60 minutes (Correct answer)
- 55 minutes
- 65 minutes
- 70 minutes
Correct answer: 60 minutes
Rate = 360/45 = 8 gal/min; 480 ÷ 8 = 60 minutes.
Question 6: An ExxonMobil report shows costs of $12M, $15M, $9M, $18M, and $11M across five divisions. What is the mean cost?
- $13M (Correct answer)
- $12M
- $14M
- $15M
Correct answer: $13M
(12+15+9+18+11) ÷ 5 = 65 ÷ 5 = $13M.
