Answer 1

Answer:

14 times

I could not give full explanation as I had less time but please mark as the brainliest and rate 5 star and say thanks.

Step-by-step explanation:

First we will Take the LCM of the 4 bells which is 504 sec or 8.5 min.

Then 1 hr = 3600 sec

2hr = 7200 sec

Then in 2 hrs they will ring together in 7200/504 times

=14.2

= 14 times(Ignore the decimal this is my way of doing)

option b is correct.
