11:30 am
Correct Answer
C
11:03 am
Your Answer
D
11:00 am

Solution

The correct option is C 11:03 am
Since the clock gains 30 secs every hour, in 6 hours, it will gain 30 × 6 = 180 secs = 3 mins.
( 60 secs = 1 min )

The accurate time after 6 hours from 05:00 am will be 11:00 am.
Since it has gained 3 mins in these 6 hours, therefore the time on the face of the clock will be 11:03 am.
