The time of a clock is 8 am. Suddenly the clock gains 10 minutes in 24 hours. Find out the original time if the time of the clock is 1 pm on the following day:
(A) 48 minutes past 12
(B) 47 minutes past 10

(C) 48 minutes past 11

(D) 48 minutes past 11




Answer: (A)

Explanation: From 8 am on a day to 1 pm on the following day will be 29 hrs.
So, the clock gains 10 min in 24 hours = 24 hrs of the correct time.
Hence, 145/6 hrs of the clock = 24 hrs of the correct clock.
29 hrs of the clock = (24 x 6/145 x 24)hrs of the correct clock = 28 hrs 48 min of the correct clock.
The correct time = 28 hrs 48 min after 8 am.
Hence, the original time is 48 minutes past 12.
