Question

Three bells ring together at 8:30 a.m. If they ring at the intervals of 4 minutes, 5 minutes and 6 minutes respectively, then at what time will they ring together
next

Answer 1

Answer:

I think next day when they will start again ring the bell

Answer 2

first bell time = 4 mins

2nd bell time = 5 mins

3rd bell time = 6 mins

in question they ask about what time will they ring together, for that we have to find LCM of times

Lcm = 4 5 6 = 120minutes

time = 8:30 + 2:00 = 10:30 AM they ring together...
