Question
Consider a circular track of circumference = 1400 m. There are 2 bikes which start from point A and move in the opposite direction. Once they meet, they start moving in the opposite directions. The one that moves in the anticlockwise direction to the other one has a speed in the ratio of 36:48 kmph. Find the distance of the two bikes from A when they meet for the 15th time?
Answer: Option C
:
C
1400 m track is divided into 7 parts of 200 m each. The speeds of the two bikes are in a ratio of 3:4, each time they meet, they will cover a distance in the ratio of 3:4

They will thus meet for the first time at 34th the distance which will happen at point 4 à 1050 m. Second time they will meet at the starting point.
3rd time at point 4... and so on.so the 15th time, they meet at 1050 cm which is 350 m from A
