A. 22.75 m B. 25 m
C. 19.5 m D.
7 4 m
7

Answer: Option B

Explanation:

 

A : B = 200 : 169.

A : C = 200 : 182.

 

C = C x A = 182 x 200 = 182 : 169.
B A B 200 169

When C covers 182 m, B covers 169 m.

 

When C covers 350 m, B covers 169 x 350 m = 325 m.
182

Therefore, C beats B by (350 – 325) m = 25 m.
