Understanding the Problem
The problem states that a faulty watch loses time. Specifically, it loses 5 minutes for every 2 hours that pass. We need to determine what time the faulty watch shows after 24 hours, starting from 6 o'clock in the morning.
Time Loss Calculation
- In 2 hours, the watch loses 5 minutes.
- In 24 hours, which is 12 times 2 hours, the total time lost can be calculated as follows:
- Total time lost = (5 minutes lost per 2 hours) x 12 = 60 minutes lost.
Actual Time Passed
- After 24 hours, the actual time that has passed is 24 hours.
- However, the faulty watch would not display this full duration due to the time loss.
Time Shown on the Faulty Watch
- Since the watch loses 60 minutes (or 1 hour) in 24 hours:
- Time shown on the faulty watch = 24 hours (actual) - 1 hour (lost) = 23 hours.
- Starting from 6:00 a.m. the previous day:
- 6:00 a.m. + 23 hours = 5:00 a.m. on the next day.
Conclusion
Therefore, on the following day at 6:00 a.m., the faulty watch shows 5:00 a.m.
Thus, the correct answer is option 'A'.

Thus, the correct answer is option 'A'.
