Question

Manoj takes 12 minutes to run around a circular track whereas Harish takes 3 minutes less to do suppose they both start at the same time and run in the same direction after how many minutes will they meet at starting point​

Answer 1

Answer:

36 minutes  

Step-by-step explanation:

Given:

Manoj takes time to complete circular path = 12 minutes

Harish takes time to complete circular path = 12 - 3 = 9 minutes

And the both meet each other at starting position only when they both on starting position.

We are finding Least Common Multiply to solve it

Since:

12 = 2×2×3

9 = 3×3

L.C.M of 12 and 9 = 2×2×3×3 = 36

So After 36 minutes both meet at starting position

Thus

Answer is 36 minutes
