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 in 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))`
`rArr (356)/(15)` h of this clock = 24 h of the correct clock
`therefore` 89 h of this clock
`= ((24 xx 15)/(356) xx 89)` h of correct clock
= 90 h of the correct clock
