Answer 1

Answer:

Firstly, take the LCM of bells interval =

LCM ( 8, 12, 18, and 20 ) = 360.

so, after 360 minutes bells will ring together.

We know that,

60 minutes = 1 hour

therefore,

360 minutes = 360/60 = 6 hours

After 6 hours means 10 am + 6hours = 4pm

so, bells will ring together at 4 pm.
