Question

7. There is a circular path around
a sports field Soria takes
18 min to drive one sound
of the field while Rani takes
12 min 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 min will they meet again at the
starting point
​

Answer 1

Answer:

They will meet after 36 minutes.

Step-by-step explanation:

Actually, here, we need to find the LCM of 18 and 12, which is 36.

Now, see:

Soria takes 18 min to make 1 round. So, in 36 min, she will make 2 rounds. Thus, she will be back at the starting point by the end of 36 mins.

Rani takes 12 min to make 1 round. So, in 36 min, she will make 3 rounds. Thus she will be back at the starting point by the end of 36 mins.

Thus, both Rani and Soria will be at the starting point after 36 mins.
