Question
In a race of 200 m, A can beat B by 31 m and C by 18 m. In a race of 350 m, C will beat B by ?
Options
A. 25 m
B. 21 m
C. 22 m
D. 19 m

Correct Answer

25 m

Explanation

A:B = 200 : 169
A:C = 200 : 182
$\frac{C}{B} = \frac{C}{A} � \frac{A}{B}$

$\frac{182}{200} � \frac{200}{169}$

=> 182:169

When C covers 182 m , B Covers 169 m
When C covers 350 m , B Covers $\frac{169}{182} � 350$
=> 325 m

So C beats B by (350 - 325) = 25 m.
