Question 1: A data center processes 4,500 transactions per hour. If the system runs for 8 hours, but experiences 45 minutes of downtime, how many transactions are processed?
- 33,375 (Correct answer)
- 36,000
- 32,625
- 34,875
Correct answer: 33,375
Uptime is 8 hours minus 0.75 hours = 7.25 hours; 7.25 × 4,500 = 33,375 transactions.
Question 2: A programmer earns $85 per hour. She works 40 hours per week and receives a 15% bonus on her monthly salary. What is her total monthly earnings (4 weeks)?
- $15,640 (Correct answer)
- $13,600
- $15,180
- $16,200
Correct answer: $15,640
Monthly base = 40 × $85 × 4 = $13,600; bonus = $13,600 × 0.15 = $2,040; total = $15,640.
Question 3: A server farm uses 3,200 kilowatt-hours of electricity per day. If electricity costs $0.12 per kilowatt-hour, how much does it cost to run the server farm for 30 days?
- $11,520 (Correct answer)
- $9,600
- $12,480
- $10,800
Correct answer: $11,520
Daily cost = 3,200 × $0.12 = $384; monthly cost = $384 × 30 = $11,520.
Question 4: An IT department has a budget of $48,000. They spend 35% on hardware, 25% on software, and the rest on training. How much is allocated to training?
- $19,200 (Correct answer)
- $16,800
- $12,000
- $14,400
Correct answer: $19,200
Hardware + software = 60% of $48,000 = $28,800; training = $48,000 − $28,800 = $19,200.
Question 5: A network transmits data at 250 megabytes per second. How long (in seconds) will it take to transfer a 7.5 gigabyte file?
- 30 (Correct answer)
- 25
- 35

Correct answer: 30
7.5 GB = 7,500 MB; 7,500 ÷ 250 = 30 seconds.
Question 6: A company orders 15 laptops at $1,240 each and receives a 12% group discount. What is the total cost after the discount?
- $16,368 (Correct answer)
- $18,600
- $17,520
- $15,840
Correct answer: $16,368
Full price = 15 × $1,240 = $18,600; discount = $18,600 × 0.12 = $2,232; total = $16,368.
