 Gain or Loss (Posted on 2003-07-05)
The minute and the hour hand of a watch meet every 65 minutes.

How much time does the watch lose or gain ?

 Submitted by Ravi Raja Rating: 3.1667 (6 votes) Solution: (Hide) The minute and the hour hand meet 11 times in 12 hours in normal watch i.e. they meet after every (12 * 60) / 11 minutes = 65.45 minutes ~ 65 minutes 27.16 seconds But in our case they meet after every 65 minutes means the watch is gaining approximately 27.16 seconds in the 65 minute interval. (This is roughly 25 seconds every hour)
