    Answer:

    \huge{\mathcal{\underline{\green{QUESTION}}}}

    Meghna cycles around a circular park in 9 minutes. Rahul cycles around the same

    park in 12 minutes. They start cycling from the same point at the same time. After

    how much time will they meet again at the starting point?

    \huge{\mathcal{\underline{\green{ANSWER}}}}

    They will be meet again after LCM of both values at the starting point.

    To get the LCM we have to factorize the number.

    18 = 2 × 3 × 3

    12 = 2 × 2 × 3

    LCM = 2 × 2 × 3 × 3 = 36

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