A person standing on a platform 160 meters long finds that a train crosses the platform in 54 sec. but himself in 30 seconds. Length of the train is

A) 100 m
B) 175 m
C) 150 m
D) 200 m

Correct Answer:




D) 200 m

Description for Correct answer:
Let length of the train is x meter.

v = \( \Large \frac{x}{30} \) ...(i)

and v = \( \Large \frac{x+160}{54} \) ...(ii)

From equations (i) and (ii), we get ' ,

x = 200 m
