Answer 1

Answer:

6 times

Step-by-step explanation:

To find when the bells will simultaneously again we have to find the LCM

LCM of 6,8,12,18=72seconds

So the bells will again ring simultaneously after 72 seconds

6 minutes=6*60=360 seconds

Number of times bells will ring in 6 minutes i.e 360 second=360/72=5 times

But the bells rang simultaneously for first time at 12 o'clock

So total number of times=5+1=6 times.
