Answer 2

Answer:

They will toll together after 60 seconds

Step-by-step explanation:

The given intervals of 5 bells are 5, 6, 10, 15, and 20 seconds

To find the time after which they will toll together for the first time we need to find the LCM of 5, 6, 10, 15, and 20

The LCM of 5, 6, 10, 15, and 20 is 60

Therefore they will toll together after 60 seconds.
