Answer:
They will next toll together at 5:07 am.
Step-by-step explanation:
There is written that the four bells toll together at intervals of 5,7,3and 12 secs,so if we find out LCM of these numbers we can get the answer form in secs that is 420 secs. We have to convert this seconds into minutes. After converting we get 7mins. So, there we got the answer that they will next toll togther after 7 mins or at 5:07 am.
