Answer: Option C
A : B = 100 : 75
B : C = 100 : 96.
A beats C by (100 - 72) m = 28 m
Answer: Option A
Ratio of the speeds of A and B = = 5 : 3
Thus, in race of 5 m, A gains 2 m over B.
2 m are gained by A in a race of 5 m.
Winning post is 200 m away from the starting point
Answer: Option B
B covers 300 m in
B runs 35 m in 7 sec.
B covers 200 m in
B's time over the course = 40 sec.
A's time over the course (40 - 7) sec = 33 sec.
