    Answer: (c) 750m
    Explanation:-

    Given –   The length of the train = length of platform = X m
    and speed of train = 90km/hr
    taken time by train across the platform = 1min

    Speed into m/sec = 90 x 5/18 = 25m/sec
    and time in sec = 1 x 60 = 60 sec.

    Distance = speed x time

    According to question,

    2X = 25 x 60 = 1500
    X = 1500/2 = 750m

    Hence, the length of the train is 750m
