Question

three bells rings at interval of 8min, 6min, and 3min respectively. if they are started together, how many times are they going to ring together in 3days

Answer 1

Answer:

Number of minutes in 3 days= 60*24*3= 4320 mins

LCM of 8,6,3

8=2*2*2

6=2*3

3=3

LCM=2*2*2*3=24

It will ring to gether after every 24 minutes

4320/24=180

therefore it will ring together 180 times in 3 days
