Total Time from 5 am. On a day to 10pm. on 4th day = 89 hours.
=> 23 hrs 44 min. of this clock = 24 hours of correct clock
=> 365/15 hrs of this clock = 24 hours of correct clock
=> 1 hrs of this clock = (24 * 15/356) hrs. of correct clock.
so, 89 hrs of this clock = ( 24 * 15/356 * 89) hrs of correct clock = 90 hrs of correct clock.
