Question

Six bells commence tolling together and toll at intervals of 2, 4, 6, 8,
10, 12 minutes respectively. In 30 hours, how many times do they toll
together?​

Answer 1

Answer:

Six bells commence tolling together and toll at intervals of 2, 4, 6, 8, 10, 12 minutes respectively.

so they will toll together when the time will be the multiple of all.

so they will toll together at LCM(2, 4, 6, 8, 10, 12)minutes

that is 120 minutes that is 2 hrs

the no of time they will toll together is 1 + 30/2 = 1 + 15 = 16

Step-by-step explanation:

we add one because at the starting they tolled together once .
