There is a circular path around a sports field. Sonia takes 18 minutes to drive one round of the field, while Ravi takes 12 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?

Solution

The correct option is B
36

Number of minutes = LCM of 18 and 12

Prime Factorisation:

12 = 2 $\times$ 2 $\times$ 3

18 = 2 $\times$ 3 $\times$ 3

L.C.M of the two numbers = $2^{2} \times 3^{2} = 36$
