Question

four bells toll at interval of 22, 33 and 55 minutes respectively. if they toll together at 10:00am, when will they toll together again?​

Answer 1

They must ring at the same time.

So we will take LCM of 22 ,33, 55

LCM = 330

so they will ring together after 330 minutes

i.e,

$\frac{330}{60} = 5hrs \: 30minutes$

i.e,at 3:30 pm
