A, B, C, D, and E practice running at a stadium that has several tracks. Each one starts running from the same point Z. A runs around a path which is an equilateral triangle ZYX. B runs around a square path ZYWV. C runs on a regular pentagonal path ZYUTS. D runs on a regular hexagonal path ZYRQPO. E runs along the trapezium ZYPO and completes one round in 20 seconds. Among all the tracks, there is a common side ZY, having length 100 m. The ratio of speeds of B and C is 5 : 4 respectively whereas the ratio of the time taken by A and D to complete one round of their tracks is 3 : 4 respectively. E's speed is the same as B's speed whereas A's speed is half that of C's.Note: The athletes maintain the same speeds in any track.Q 113.   If A, B and C start running in the same direction along a 300 m long circular track, then after how much time will they meet for the first time?a)  60 secondsb)  90 secondsc)  75 secondsd)  120 seconds

A fun run has a choice of two routes as shown below.The long route is around the whole perimeter of the shape 𝐴⁢𝐵⁢𝐶⁢𝐷, starting and finishing at 𝐴.The short route is around the rectangle 𝐴⁢𝐵⁢𝐸⁢𝐹, starting and finishing at 𝐴.

A, B and C start at the same time in the same direction to run around a circular stadium. A completes a round in 252 seconds, B in 308 seconds and c in 198 seconds, all starting at the same point. After what time will they again at the starting point ?

X, Y, Z start at the same time in the same direction to run around a circular stadium. X completes a round in 63 seconds, Y in 105 seconds and Z in 210 seconds. If they start at the same time, then at what time will they meet again at the starting point?

Two trains running in opposite directions cross a man standing on the platform in 27 seconds and 17 seconds respectively and they cross each other in 23 seconds. The ratio of their speeds is:*1 point3:4None of these3:21:3

Aman and Babli run around a circular track of length L metres. Aman and Babli run at constant, but different speeds. They start from diametrically opposite points such that Aman runs clockwise around the track and Babli runs counterclockwise. They meet for the first time after Aman has run 100 metres and for the second time after Babli runs 150 metres past their first meeting point. What is the value of L?
