USA Occupational Math Assessment 4 — Questions and Answers
Question 1: A worker completes 5/8 of a project on Monday and 1/4 of the project on Tuesday. What fraction of the project remains?
- 1/8 (Correct answer)
- 3/16
- 1/4
- 3/8
Correct answer: 1/8
Work done = 5/8 + 2/8 = 7/8; remaining = 1 − 7/8 = 1/8.
Question 2: A forklift can carry a maximum load of 4,500 pounds. A pallet of boxes weighs 325 pounds each. What is the maximum number of full pallets the forklift can carry in one trip?
- 12 pallets
- 13 pallets (Correct answer)
- 14 pallets
- 15 pallets
Correct answer: 13 pallets
4,500 ÷ 325 = 13.84; the forklift can carry 13 complete pallets.
Question 3: A job site uses 3 workers to complete a task in 12 days. If 4 workers are assigned instead, approximately how many days will the same task take?
- 7 days
- 8 days
- 9 days (Correct answer)
- 10 days
Correct answer: 9 days
Total work = 3 × 12 = 36 worker-days; days with 4 workers = 36 ÷ 4 = 9 days.
Question 4: An invoice shows: Item A $234.80, Item B $87.50, Item C $312.00, minus a $50 credit. What is the total amount due?
- $584.30 (Correct answer)
- $584.80
- $634.30
- $634.80
Correct answer: $584.30
$234.80 + $87.50 + $312.00 = $634.30; minus $50 credit = $584.30.
Question 5: A gauge reading shows a pressure of 72 PSI. The target pressure is 85 PSI. By what percentage is the current pressure below the target?
- 13.0%
- 15.3% (Correct answer)
- 17.8%
- 18.1%
Correct answer: 15.3%
Difference = 85 − 72 = 13 PSI; percentage = (13 ÷ 85) × 100 ≈ 15.3%.
Question 6: A warehouse receives a shipment of 1,200 items. Quality control rejects 4.5% as defective. How many items pass inspection?
- 1,138
- 1,146 (Correct answer)
- 1,152
- 1,160
Correct answer: 1,146
Rejected = 1,200 × 0.045 = 54; passing = 1,200 − 54 = 1,146 items.
Question 7: A heating system uses 2.5 gallons of fuel oil per hour. The fuel tank holds 200 gallons and is currently at 40% capacity. How many hours can the system run before the tank is empty?
- 28 hours
- 32 hours (Correct answer)
- 36 hours
- 40 hours
Correct answer: 32 hours
Fuel available = 200 × 0.40 = 80 gallons; hours = 80 ÷ 2.5 = 32 hours.
