Question

5 bells begin tolling together and toll at intervals of 2, 6, 8 , 10 and 12 seconds respectively. In 45 minutes how many times do they toll together?​

Answer 1

Answer:

11 TIMES

Step-by-step explanation:

They toll together at the zeroth second.

The next time they toll together = LCM(2,5,6,8,9) = 360 seconds = 6 minutes

Every 6 minutes, they toll together.

In an hour(60 mins), they toll together (60/6)+1 = 11 times

1 is added because they toll at the zeroth second. 0,6,12,18,24,30,36,42,48,54,60
