Answer 1

Answer:

Step-by-step explanation:

The clocks chime at intervals of 15, 20, 30 minutes respectively..

All chime together at 2 pm.

All will together chime again in LCM of 15, 20 and 30 minutes.

So the LCM is 60 min or 1 hour.

So they will chime again at 3 pm, then at 4 pm, at 5 pm and so on.
