A watch which gains uniformly is 2 minutes slow at noon on Monday and is 4 min 48 sec fast at 2 PM on the following Monday. When was it correct?

Correct Answer: B — 2 PM on Wednesday

Explanation:

The correct answer is 2 PM on Wednesday. Total gain over 170 hours = 2 + 4.8 = 6.8 minutes. The watch was correct after gaining 2 minutes from Monday noon: (2/6.8) Ã— 170 = 50 hours later = 2 PM on Wednesday.
