A train passes a station platform in 36 seconds and a man standing on the platform in 20 seconds. If the speed of the train is 126 km/hr, what is the length of the platform?
Select the correct option:
A) 338	B) 240	C) 560	D) 267	E) 191
Speed = (126 * 5/18) m/sec = 35 m/sec. Length of the train = (35 x 20)m = 700 m. Let the length of the platform be x meters. Then, (x + 700)/36 = 35 ==&gt; x + 700 = 1260 ==&gt;   x = 560 m.   Answer: 560
