Question

13. At a temple a bell rings every 40 minutes and the city clock tower rings every 60 minutes. At 6 am on a da
both the bells sounded together. At what time will both of them make their sound simultaneously next time?​

Answer 1

Answer:

8 am

Explanation:

frequency of temple bell = 40 mins

frequency of city clock tower = 60 mins

therefore, LCM of 40 and 60 = 120

therefore, both bells will ring simultaneosly after 120 mins

= 2 hrs

therefore, 6 am + 2 hrs = 8 am
