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:	Choose the correct choice:	A) 33	B) 25	C) 88	D) 29	E) 10
A : B = 200 : 169.   A : C = 200 : 182.   \inline \fn_jvn {\color{Black} \frac{C}{B}=\left ( \frac{C}{A}\times \frac{A}{B} \right )=\left ( \frac{182}{200}\times \frac{200}{169} \right )=182:169}   When C covers 182 m, B covers 169 m.   When C covers 350 m, B covers \inline \fn_jvn {\color{Black}\left ( \frac{169}{182}\times 350 \right )m} = 325 m   Therefore, C beats B by   (350 - 325)=
