Question

Two clocks are set correctly at 9 am on monday. Both the clocks gain 3 min and 5 min respectively in an hour. What time will the second clock register, if the first clock which gains 3 min in an hour shows the time as 27 min past 6 pm on the same day?

Answer 1

The time that elapses from 9 am to 6 pm on the same day is 9 hours. So the

first clock gains  9×3=27   minutes

and shows the time as 6:27 pm, while the

second clock gains   9×5=45  minutes

and shows the time as 6:45 pm

Two clocks are set correctly at 9 am on monday. Both the clocks gain 3 min and 5 min respectively in an hour.
