- QUESTION
A clock is set right at 10 am. The clock gains 10 minutes in a day. What will be the true time when the watch indicates 3 pm the next day?
A)12 minutes past 2 pm
B)45 minutes past 2 pm
C)32 minutes past 2 pm
D)48 minutes past 2 pm
Explanation
(D)= 48 minutes past 2 pm
= Clock gain in 24 hours = 10 mint
Clock gain in 1 hour = 10/24 mint
Number of hours when clock indicate 3 pm on the following day = 24+529 hours.
So, clock gain in 29 hours = 29 × 10/24 = 12 minutes
Hence, Right time = 12 minutes to go to 3 P.M. = 2:48 Ρ.Μ
