A train crosses a platform of 150 m in 15 sec, same train crosses another platform of length 250 m in 20 sec. then find the length of the train?  Choose the correct choice:	A) 150 m	B) 165 m	C) 155 m	D) 160 m	E) 170 m
Length of the train be ‘X’   X + 150/15 = X + 250/20   4X + 600 = 3X + 750   X = 150m   150 mNSWER:150 m
