E)6.26
for every 5min watch looses 2secs, so for 60ms it looses 24 sec,
ie., fo 1hr it looses 24 secs
8.30amto6.30pm=10hr it looses 240secs ie., 4mins , hence d watch wil show 6.26

(E)6.26
8.30 a.m. to 6.30 p.m. takes 10 hr.

In 5 min watch loses 2 sec
1 min loses 2/5 sec
60 min loses=(2/5)*60 sec
10*60 min loses=(2/5)*60*10 sec
10 hr loses=240 sec i.e.4 min loses
so,6.26

Minutes b/w 8.30 am & 6.30pm = 10hours=600mins
From given: If 5min=loss of 2seconds then 600mins = 240seconds..(i.e) 4 minutes
Therefore 4 minutes is subtracted from 6.30 pm we get 6:26 pm
Ans : 6.26 pm

Watch was set at 8.30 am.
For each 5 mins, it loses 2 secs.
Then for 1 hr , there is (60/5)=12 (5)mins.
But it loses 12*2=24 secs for 1 hr
Time between 8.30 am to 6.30 pm is 10 hr . The lose of time is 10*24=240 seconds. i.e 4 mins lose
6.30-0.04=6.26pm

Ans:- (E) 6.26
