Algorithms Quiz | Sudo Placement [1.5] | Question 5
A and B started running on a circular track (in the same direction) of 300 m with speed 2 m / s and 3 m / s respectively. After how much time they will meet at starting point for the first time?
(A) 2 min
(B) 3 min
(C) 4 min
(D) 5 min
Explanation: Time taken by A = 300 / 2 = 150 sec.
Time taken by B = 300 / 3 = 100 sec.
For meeting at starting point for the first time take lcm of time taken by both A and B.
I.e. LCM (150, 100) = 300 sec = 5 minute.
