Four bells ring at intervals of 6, 8, 12 & 20 minutes. They ring s...
Required time = LCM of 6, 8, 12 and 20
∴ Required time = 2 × 2 × 3 × 2 × 5
= 120 minutes = 2 hr.
∴ bell will again ring together at (7 + 2)
= 9 a.m.
∴ Required time = 2 × 2 × 3 × 2 × 5
= 120 minutes = 2 hr.
∴ bell will again ring together at (7 + 2)
= 9 a.m.

Four bells ring at intervals of 6, 8, 12 & 20 minutes. They ring s...
To find the time when all four bells will ring together, we need to find the least common multiple (LCM) of 6, 8, and 12.
First, we list the multiples of each number:
Multiples of 6: 6, 12, 18, 24, 30, ...
Multiples of 8: 8, 16, 24, 32, 40, ...
Multiples of 12: 12, 24, 36, 48, 60, ...
From this list, we can see that the least common multiple of 6, 8, and 12 is 24.
Therefore, all four bells will ring together every 24 minutes.
