In a 200 metres race A beats B by 35 m or 7 seconds. A's time over the course is:

A. 40 sec

B. 47 sec

C. 33 sec

D. None of these

Answer: Option C

Solution(By Examveda Team)

B runs 35m in 7sec
∴ B covers 200m in $$ {\frac{7}{{35}} \times 200} = 40\sec $$
B's time over the course = 40 sec
∴ A's time over the course (40 - 7) sec = 33 sec
