The length of a train and that of a platform are equal. If with a speed of 126 k/hr, the train crosses the platform in one minute, then the length of the train (in meters) is?
Options:
A) 227
B) 299
C) 1050
D) 750
E) 211

Rationale: "speed = [ 126 * 5 / 18 ] m / sec = 35 m / sec ; time = 1 min . = 60 sec . let the length of the train and that of the platform be x meters . then , 2 x / 60 = 35 è x = 35 * 60 / 2 = 1050 answer : c"
Answer: C
