Question
A, B and C start running around a circular track and
complete one round in 10, 15 and 25 seconds respectively. In how many seconds will the three meet again at the starting point if they all have started running at the same time?Solution
As A, B and C complete one round in 10, 15 and 25 seconds respectively, they will be able to meet at the starting point only if we get a common multiple of 10, 15 and 25. To meet for the second time, we need to calculate LCM. LCM (10,15,25) = 150 ∴ They will meet again in 150 seconds.
