Need answer with clr

Yes actually 22 Times ...

and i can justify when you say @ranjithpvrp

Yeah its crt but need how

First overlap happens after T = 12/11 hours. Similarly, the second time they overlap, the minute hand would have completed two more laps than the hour hand. So for N overlaps, we have T = T/12 + N. Thus, the hands of a clock overlap 22 times a day.
