Each line above represents the hands of the clock.

There are 6 intevals, so the clock takes 7 seconds for covering 6 intervals.

Similarly, there would be 9 intevals for striking 10.

By unitary method,

Interval. Time

6. 7

9. ?

Threfore, we get the value as 10.5

∴It takes 10.5 seconds for the clock to stike 10
