Question

The three different bells at different testing machines in a laboratory ring after 48 min, 60 min and 84 min respectively. If they ring simultaneously at 1 a.m. today, at what time will they ring simultaneously again?

Answer 1

The time they will ring again must be- 1 am + (LCM of 48, 60 and 84)

LCM is 1680.

1680 mins= 28 hours

Therefore, they will ring at 1 am+ 28 hours simultaneously again, = 5 am the next day.
