Assume the two of them start at a similar point and simultaneously, and head a similar way. After how long will they meet again at the beginning stage?

There is a roundabout way around a games field. Sonia requires 18 minutes to drive one round of the field, while Ravi requires 12 minutes for the equivalent. Assume the two of them start at a similar point and simultaneously, and head a similar way. After how long will they meet again at the beginning stage?

Solution:

Since, Both Sonia and Ravi move a similar way and simultaneously, the technique to make when they will meet again at the beginning stage is LCM of 18 and 12.

Consequently, LCM(18,12) = 2×3×3×2×1=36

Consequently, Sonia and Ravi will meet again at the beginning stage following 36 minutes.
