Ram, Rajesh, and Suresh start running around a circular track and complete one round in 20 seconds 60 seconds and 50 seconds respectively. In how many seconds will the three meet at the starting point if they all have started running at the same time? Correct Answer 300 seconds

Calculation:

⇒ The required time = LCM (20, 60, 50)

⇒ The required time = 300 seconds

∴ The required result will be 300 seconds.

Important Points

The intervals at which they will meet each other = multiples of the LCM of the time taken by individuals to cover the track.
