Answer 2

At 6'0 clock the clock strikes 6 times, so there will be 5 intervals in between the strikes.

The clock takes 10 seconds for 5 intervals.

So 10/5 = 2 seconds for 1 interval.

At 12'0 clock, the clock will strike 12 times.

So there will be 11 intervals in between.

So time required to strike at 12'o clock = 11*2 = 22 seconds

Time taken by it too strike at 12'o clock is 22 seconds
