Question

6 balls commence tolling together and at interval of 2 4 6 8 10 12 respectively .In 30 minute how many times do they toll​

Answer 1

Answer:

The bells will toll together when there is one time interval which is divided by every single time interval.

Thus, we need to find the LCM of 2,4,6,8,10,12

LCM : 120

Thus, in 30 minutes = 30 * 60 seconds, they will toll together:

30∗60/120

= 15
