A clock is set right at 8 a.m. The clock gains 10 minutes in 24 hours. What will be the true time when the clock indicates 1 p.m. on the following day?
A. 46 minutes past 12
B. 48 minutes past 12

D. 47 minutes past 12
Answer: Option B
Solution (By JKSSB Mock Tests)
From 8 a.m. to 1 p.m. next day is 29 hours. The clock gains 10 min in 24 hours, so in 29 hours gains (10/24)×29 = 145/12 ≈12.083 min. When clock shows 29 hours, actual time passed is 29 - 12.083/60 hours ≈28 hours 47.9 min, so true time is about 12:48 p.m. Standard answer is 48 min past 12.
