EDPT Arithmetic Reasoning Word Problems 5 — Questions and Answers
Question 1: A database contains 1,250,000 records. A cleanup script deletes 4% of the records. How many records remain?
- 1,200,000 (Correct answer)
- 1,100,000
- 1,150,000
- 1,225,000
Correct answer: 1,200,000
Deleted = 1,250,000 × 0.04 = 50,000; remaining = 1,250,000 − 50,000 = 1,200,000.
Question 2: A project manager divides a $96,000 budget among 4 teams in the ratio 3:2:2:1. How much does the largest team receive?
- $36,000 (Correct answer)
- $24,000
- $32,000
- $12,000
Correct answer: $36,000
Total parts = 3+2+2+1 = 8; largest team share = (3/8) × $96,000 = $36,000.
Question 3: An internet connection downloads at 50 Mbps. A company downloads 18,000 MB of data. How many minutes does the download take?
- 6 (Correct answer)
- 360
- 3
- 300
Correct answer: 6
Time in seconds = 18,000 MB ÷ 50 Mbps = 360 seconds = 6 minutes.
Question 4: A help desk resolves 80% of tickets on the first call. If they receive 475 calls on Monday, how many tickets are NOT resolved on the first call?
- 95 (Correct answer)
- 380
- 80
- 100
Correct answer: 95
Resolved = 475 × 0.80 = 380; not resolved = 475 − 380 = 95.
Question 5: An IT contractor works 4 days per week, 9 hours per day, and charges $75 per hour. How much does she earn in a 4-week month?
- $10,800 (Correct answer)
- $8,100
- $12,600
- $9,600
Correct answer: $10,800
Weekly hours = 4 × 9 = 36; weekly pay = 36 × $75 = $2,700; monthly = $2,700 × 4 = $10,800.
Question 6: A quality control team finds 3 defective units per every 500 units inspected. If they inspect 12,000 units, how many are defective?
- 72 (Correct answer)
- 60
- 36
- 84
Correct answer: 72
Defect rate = 3/500; defective units = (3/500) × 12,000 = 72.
Question 7: A company rents server space for $350 per month. They negotiate a 2-year contract with a 15% annual discount. How much do they save over the 2-year contract?
- $1,260 (Correct answer)
- $630
- $840
- $1,050
Correct answer: $1,260
Annual cost = $350 × 12 = $4,200; 15% discount = $4,200 × 0.15 = $630/year; 2-year savings = $630 × 2 = $1,260.
