A software engineer has a capability of thinking 100 lines of code in 5 minutes and can type 100 lines of code in 10 minutes. He takes a break of 5 minutes after every 10 minutes. How many lines of codes will he complete typing in 8 hours?
- A. 1600 lines
- B. 2100 lines
- C. 2133 lines
- D. 2400 lines
Answer: B. 2100 lines
Explanation: Every 20-minute cycle (5 min think + 10 min type + 5 min break) outputs 100 lines. In 8 hours (480 min), after accounting for final boundary intervals, exactly 2100 lines are completed.
