Question

There is a circular path around a sport field. Seema takes 20 minutes to drive one round of the field, while Aarti takes 16 minutes for the same. Suppose they both start at the same point and at the same time, and go in the same direction. After how many minutes will they meet again at the starting point?

Answer 1

Answer:

simply take the lcm and you will get the answer

Answer 2

Answer:

ANSWER

Sonia and Ravi drive one round of the field in same point, same time and same direction.

So, they will meet again after LCM of both values at the starting point.

To get the LCM we have factorize the number.

Factor of 18=2×3×3

Factor of 12=2×2×3

LCM =2×2×3×3=36

Hence, they will meet together at the starting point after 36 minutes.
