PLEASE MARK IT THE BRAINLIEST ANSWER!!!!

Answer 2

They will toll together again after an interval of time which will be multiple of 12,15 and 18 as well.

So, we have to find out the LCM of these three numbers

12= 2*2*3
15= 3*5
18= 2*3*3
LCM of 12,15 and 18 is
=2²*3²*5
=180

so the bells will ring together after 180 min.
