1. A watch gains 7 minutes and 6 seconds every 6 days. if the rate of gain is constant, how much does the watch gain in one day?
- A. 1 min 6 sec
- B. 1 min 6 sec
- C. 1 min 6 sec
- D. 1 min 6 sec
Answer: Option B
Explanation:
Here, 7 min 6 sec = 7×60 + 6 sec = 426 sec
The clock in 6 days gains = 426 sec
So, the clock in 1 day gains = 426/6 = 71 sec = 1 min 11 sec
