The answer is 3:59:35 PM.
7 am to 4:15 PM is 9hrs and 15 mins.
Given:
gains 5 secs in 3 mins
so 100 secs in 60 mins
so 925 secs in 9 hours and 15 mins
So at 4:15 subtract 925 secs or 15 mins and 25 secs.
So it will be 3:59:35

Answer / vivek
the answer is 4:00 pm.
7 am to 4:15 PM is 9hrs and 15 mins.
3mins = 180 sec
after 3 mins watch shows 3min 5 sec i.e. 185 secs.
gain 5 sec in 185 sec
then in 555*60 sec =( 5/185)*555*60 =900sec=15min
so subtract 15 min from 4:15 the right answer is 4:00pm
