as per given situation the clock gains 12 min per 12 hour means 1 minute per hour
so if i set it today 11am the till the day ends it would have gained 13 minutes as
24 hr - 11 = 13
now for next five days it will gain
5*24 = 120 minutes
on 6th day till 1pm it will gain
13 minutes more
so. total gain
13+120+13 = 146
which is 2hour 26 minutes
so at 1PM. its will show 3:26PM
