Correct Answer: 52. (5)
Solution: 52. (5) When a train crosses a platform, the distance covered $=$ length of train and platform
$\therefore$ If the length of train be $x$ metre,
Speed $=\frac{\text { Distance }}{\text { Time }}$
$\Rightarrow 72 \times \frac{5}{18}=\frac{x+524}{55}$
$\Rightarrow 20 \times 55=x+524$
$\Rightarrow x+524=1100$
$\Rightarrow x=1100-524$
$=576$ metre
