A train passes a station platform in 32 seconds and a man standing on the platform in 20 seconds. If the speed of the train is 54 km/hr, what is the length of the platform?
Choose the correct choice from the following choices:
A) 180 m
B) 240 m
C) 300 m
D) 360 m
E) 280 m
Speed = 54 x	5/18	m/sec = 15 m/sec.   Length of the train = (15 x 20)m = 300 m.   Let the length of the platform be x metres.   Then,	(x + 300)/32	= 15   x + 300 = 480   x = 180 m.180 mnswer: Option 180 m
