There is a circular path around a sports field. Rahul takes 15 minutes to drive one round of the field, while Anil takes 18 minutes for the same. Suppose they both start from the same point and at the same time, and go in the same direction. After how many minutes will they neet again at the starting point?
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. 90.
Given:
Time taken by Rahul to drive one round = 15 min
Time taken by Anil to drive one round = 18 min
Concept used:
LCM method
Calculations:
When they are moving in a circular field from the same point and at the same time.
The required time at which they will meet again (LCM of 15 and 18) = 90
