Question

Three clocks in a shop ring at intervals of 6 minutes, 14 minutes and 24 minutes. If they
ring together at 8:45 am, at what time will they ring together again ?​

Answer 1

Answer: 11:33 AM

Step-by-step explanation:

The three clocks will again ring together at the LCM of the time after which they ring.

So, we have to find the LCM of 6,14 and 24.

6 = 2 × 3

14 = 2 × 7

24 = 2 × 2 × 2 × 3

LCM(6,14,24) = 168

So, they will ring again together after 168 minutes.

So, they will ring again at 11:33 AM.
