3 bells ring at interval of 10min,12min,and 15min.if they last rang together at 9:25a.m ,at what time are likely to ring together next?

The next time the bells will ring together is when the time is a multiple of all three intervals, which is 60 minutes (10 x 12 x 15 = 1800 minutes = 60 minutes x 30).

Since the bells last rang together at 9:25 a.m., the next time they are likely to ring together is 60 minutes later, which is at 10:25 a.m.

To find the next time the bells will ring together, we need to find the LCM (Least Common Multiple) of their ringing intervals.

LCM of 10, 12, and 15 is 60.

This means that the bells will ring together again after every 60 minutes or 1 hour.

Since they last rang together at 9:25 AM, they will ring together again at:

9:25 AM + 1 hour = 10:25 AM
