Correct Answer - Option 2 : 7.30

A clock completes a full rotation in 12 hours i.e., in 12 hours a clock covers an angle of 360o.

Therefore, time taken to cover an angle of 135o = (12/360 × 135) hours 

= 4.5 hours

= 4 hours 30 minutes

So, 3.00 + 4 hours 30 minutes

= 7 hours 30 minutes 

So, the clock which shows accurate time as 3.00, will show 7.30 after the hour hand has moved 135o.

Hence, ‘7.30’ is the correct answer.
