We know that if we have to find the first meeting of all these Bells then we have to find out the LCM of all these
then LCM =108
So they will again meet after 1minute 48sec.

Four bells ring at intervals 6, 12, 18, 27 seconds. They starts ringin...
Given Information:
- Four bells ring at intervals of 6, 12, 18, and 27 seconds.
- They start ringing simultaneously at 8 o'clock.

To Find:
- When will they ring again together?

Explanation:

The given intervals of the four bells are 6, 12, 18, and 27 seconds. To find the time when they will ring again together, we need to find the least common multiple (LCM) of these intervals.

Finding the LCM:
To find the LCM of the given intervals, we can list the multiples of each interval until we find a common multiple.

For 6 seconds:
Multiples of 6: 6, 12, 18, 24, 30, 36, 42, ...

For 12 seconds:
Multiples of 12: 12, 24, 36, 48, 60, ...

For 18 seconds:
Multiples of 18: 18, 36, 54, 72, ...

For 27 seconds:
Multiples of 27: 27, 54, 81, ...

The first common multiple we find is 54 seconds. Therefore, the LCM of the given intervals is 54 seconds.

Calculating the Time:
The bells start ringing simultaneously at 8 o'clock, which means they will ring again together after a multiple of 54 seconds.

To calculate the time, we convert 54 seconds into minutes and seconds:
54 seconds = 0 minutes 54 seconds

Therefore, the bells will ring again together 0 minutes and 54 seconds past 8 o'clock.

Conclusion:
The correct answer is option A) 1 minute 12 seconds past 8.
