Time from 5 a.m. on a day to 10 p.m. on 4th day = 89 hours.

(ஃDay 1 --> 19, Day 2 --> 24, Day 3 --> 24, Day 4 --> 22)

If the clock loses 16 min for 24 hours, then it will lose (16/24) --> 2/3 min per hour.

The clock will lose for 89 hours --> 89 x (2/3)

≈59.33

So, the true time will be approx. 60 min more, that is 11 p.m

As the clock loses 16minutes in 24 hours, so in 1 hour it loses 16/24hrs i.e. 2/3 hrs.
From the 1st day(5am) to 4th day(5 am) it will lose 16x3=48mins.
On the 4th day there is 17 hrs from 5am to 10pm i.e. equal to 17 hrs.
So in 17 hrs the clock will lose 17x(2/3)= 34/3= 11mins 20 seconds
So total minutes the clock has lost is 48mins+11mins 20 seconds= 59 mins 2 seconds = 1 hour (appx.)
So the true time will be 10+1= 11pm
