Explanation:

This sunday morning at 8:00 AM, the watch is 5 min. Slow, and the next sunday at 8:00PM it becomes 5 min 48 sec fast.
The watch gains 5+54860 min in a time of (7×24)+12 = 180 hours.
To show the correct time, it has to gain 5 min.
545min→180hours
5min ->
5542×180
8313hrs=72hrs+1113hrs=3days+11hrs+20min
So the correct time will be shown on wednesday at 7:20 PM
