Answer:
mani and Ravi start from the same point, at same time and in same direction. So they meet again after lcm of the times taken by them individually To get the LCM we have to factorize the numbers,
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.
