Given,

The clock is set at 9 am

gains 1 min in the first 3hrs

looses 1 min in every fourth hour

To find,

The time the clock will show at 1:00 pm the next day

Solution

3 hours from 9 am is 12 pm. The time shown on the clock is 12:01.

4 hours from 9 am is 1 pm. The time shown at 1 pm will be 1:00

Another 4 hours from 1 pm will be 5 pm. The time shown at 5 pm is 4:59

Another 4 hours from 5 pm will be 9 pm. The time shown at 9 pm is 8:58

Another 4 hours from 9 pm will be 1 am. The time shown at 1 am is 12:57

Another 4 hours from 1 am will be 5 am. The time shown at 5 am is 4:56

Another 4 hours from 5 am will be 9 am. The time shown at 9 am is 8:55

Another 4 hours from 9 am will be 1 pm. The time shown at 1 pm is 12:54

Thus, the clock will show the time of 12:54 at 1 pm the next day.
