Question

There is a circular path around a sports field. Priya takes 18 minutes to drive one round of the field,while Ravish takes 12 minutes for the same. Suppose they both start at the same point and,and go in the same direction . After how many minutes will they meet again at the starting point

Answer 1

LCM OF 18 AND 12 IS 36

AND HENCE THEY WILL MEET AFTER 36MINUTES

Answer 2

Well we have to find after how many minutes they both will meet again.

So we should have to find the least Common multiple of the numbers :

Solution :

Finding the least Common multiple :

18 = 2 × 3 × 3

12 = 2 × 2 × 3

Least Common Multiple =

2² × 3³ = 36

Hence , Ravish and Priya will meet after 36 minutes.
