Answer 1

Question:-

Three bells ring regularly at intervals of 4, 7 and 14 minutes if all three Bells Rang together at 6:00 a.m. when will they ring together again.

Solution:-

The intervals of ringing of these 3 bells are 4,7 and 14 minutes. 

so, Minimum time after which these all 3 bells will ring = LCM(4,7,14) = 28 min. 

so, After 28 minutes , these all 3 bells will ring together. 

And, so, these bells will ring together at 6:28 am.

Answer 2

Answer :

Hey Mate,

The three bells rang at the intervals of 4, 7 and 14 Mins.

So, We need to find out the LCM of 4 ,7 , And 14.

LCM of 4 , 7 , 14 = 28.

So, the all three bell rang together after every 28 Mins.

Or The next time all three bell rang together at 6:28 A. M ( Morning ).
