A train traveling at 72 kmph crosses a platform in 33 seconds and a man standing on the platform in 18 seconds. What is the length of the platform in meters?
Choose the correct choice from the following answers:	A) 240 meters	B) 360 meters	C) 420 meters	D) 300 meters	E) Cannot be determined
Speed of train = 72 * (5/18)=

<output>20</output>
20 m/s   Lets consider the man as a stationery point on the platform.   Crossing the point gives us the length of the train.   Lt= 20 * 18=

<output>360</output>
360 m.   Crossing the platform gives us the length of trainlength of platform.   L(t+p)= 20 * 33= 
<gadget id="calculator">20 * 33</gadget>
<output>660</output>
660 m.   So, length of platform= 660 - 360= 
<gadget id="calculator">660 - 360</gadget>
<output>300</output>
300 m   IMO, Answer   300 meters
<result>D</result>
