EDPT (Electronic Data Processing Test) Numerical Reasoning 2 — Questions and Answers
Question 1: A server processes 1,440 transactions per hour. How many transactions does it process per minute?
- 24 (Correct answer)
- 14
- 20
- 12
Correct answer: 24
1,440 ÷ 60 minutes = 24 transactions per minute.
Question 2: A dataset grows from 250 MB to 400 MB. What is the percentage increase?
- 60% (Correct answer)
- 37.5%
- 150%
- 62.5%
Correct answer: 60%
(400 − 250) ÷ 250 × 100 = 60%.
Question 3: If 5 programmers can complete a project in 12 days, how many days will 3 programmers need for the same project?
- 20 (Correct answer)
- 18
- 15
- 7
Correct answer: 20
Total work = 5 × 12 = 60 programmer-days; 60 ÷ 3 = 20 days.
Question 4: A binary number 1011 converted to decimal is:
- 11 (Correct answer)
- 13
- 9
- 15
Correct answer: 11
1×8 + 0×4 + 1×2 + 1×1 = 8+0+2+1 = 11.
Question 5: A network transfers data at 8 Mbps. How long (in seconds) does it take to transfer a 40 MB file?
- 40 (Correct answer)
- 5
- 80
- 320
Correct answer: 40
40 MB = 320 Mb; 320 Mb ÷ 8 Mbps = 40 seconds.
Question 6: If the average of six numbers is 15, what is their sum?
- 90 (Correct answer)
- 21
- 9
- 15
Correct answer: 90
Sum = average × count = 15 × 6 = 90.
Question 7: A storage array uses 3 out of every 4 sectors for data and the rest for parity. If there are 256 total sectors, how many are used for parity?
- 64 (Correct answer)
- 48
- 32
- 192
Correct answer: 64
1/4 of 256 = 64 sectors used for parity.
