    Answer: (4) 270 m
    Explanation:-
    Let the length of the goods train be  = X m
    The speed of the goods train = 72 km/hr
    Speed in m/sec = 72 x 5/18 = 20 m/sec
    The length of the platform = 250 m

    Total distance covered by train = (X + 250) m
    Time taken by train to cross the platform = 26 sec

    Formula-
    Time = Distance/speed
    Then, (X + 250) /20 = 26
    X + 250 = 26 x 20
    X = 520 – 250
    X = 270 m
    Hence, the length of the goods train is 270 m.
