Question

FOUR BELLS TOLL AFTER AN INTERVAL OF 8,9,12 AND 15 SECONDS RESPECTIVELY. WHEN WILL THEY TOLL AGAIN? ​

Answer 1

Answer:

after 6 minutes.

Step-by-step explanation:

The interval = 8, 9, 12, and 15 second.

we have to find out the LCM of these numbers.

Hence,

after 360 second they'll toll together.
