If in a 200 m race, A beats B by 31 m and C by 18 m, then in a 350 m race, C will beat B by
Answer & explanation
Correct answer: option 3
The correct answer is Option (3) → 25 m
Let the speed of A, B and C be $S_A,S_B$ and $S_C$ respectively.
$⇒\frac{S_B}{S_A}=\frac{169}{200}$ and $\frac{S_C}{S_A}=\frac{182}{200}$
$⇒\frac{S_B}{S_C}=\frac{169}{182}$
∴ Distance covered by $B=\frac{169}{182}×350$
$=325.55m$
∴ Difference = $350-325.55≃25m$
