Explanation by: Admin
Time from 5 am of a particular day to 10 pm on the 4th day is 89 h. Now, the clock loses 16 min in 24 h or on other words, we can say that 23 h 44 min of this clock is equal to 24 h of the correct clock. or (23 + 44/60)
⇒ 356 h of this clock = 24 h of the correct clock
∴ 89 h of this clock
= (24 x 15/356 x 89) h of correct clock
= 90 h of the correct clock
