Question

number of times will 5 bells ring together in 1 hour if they start together and ring at intervals of 2,3,4,5and 6 sec respectively is​

Answer 1

Answer:

60 times

Step-by-step explanation:

if 5 bells ring at intervals 2,3,4,5 and 6 sec, when started together, they will ring together again after a period equal to the least common divisor ( LCM) of the intervals

The least common divisor  of the 5 intervals is 60.

Therefore when started together, the five bells ring together after time period of  60 seconds or 1 minute.

In a time period of 1 hour, they will 60 times (since one hour consists of 60 minutes)
