Amit, Sucheta and Neeti start running around a circular track and complete one round in 18 s, 24 s and 32 s, respectively. In how many seconds, will the three meet again at the starting point as they all have started running at the same time?
[IOB (PO), 2009]
Explanation
Here, to find out the time after which they meet again at the starting point
= LCM of 18, 24 and 32
=288 s
∴ After 288 s they will meet with one another.
Hence, Option B is correct.
