$A$ and $B$ can cover a 200 m race in 22 seconds and 25 seconds respectively. When $A$ finished the race, then $B$ is at what distance from the finishing line?
(a)24 m
(b)30 m
(c)48 m
(d)54 m (Railways, 2004)
Answer
Answer (as printed): A
Explanation
Distance covered by $B$ in $25 \mathrm{sec}=200 \mathrm{m}$. Distance covered by $B$ in 22 sec. $=\left(\frac{200}{25} \times 22\right) \mathrm{m}=176 \mathrm{m}$. $\therefore B$ was at a distance of $(200-176) \mathrm{m}=24 \mathrm{m}$ from the finishing line.
