Explanation:
Hi.
This problem based on the concept of LCM.
Here we have to find LCM of intervals
9,12,15 minutes which indicates
after how long they all again tall
together.
write 9,12,and 15 product of prime
factors,
9=3×3
12=2×2×3
15=3×5
LCM (9,12, 15 ) =3×3×2×2×5
=180
Three bell toll together after 180
minutes.
I hope this will useful to you.
