Question

5) Six bells commence tolling together and toll at the interval of 2, 4, 6, 8, 10, 12
minutes respectively. How many times do they toll together in 30 hours?
​

Answer 1

Answer:

The least common multiple (LCM) of 2, 4, 6, 8, 10, and 12 is 120. Thus, the bells toll together every 120 seconds (or 2 minutes), so in 30 minutes they will toll simultaneously 30/2 = 15 times.
