    B 128 Correct Answer Incorrect Answer
    C 118 Correct Answer Incorrect Answer
    D 148 Correct Answer Incorrect Answer

    Solution

    Let the length of the train be x m. Length of the platform = 204 m As we know, Speed = Distance/time (x+204)/57 = x/23 23x + 4692 = 57x 57x-23x = 4692 34x = 4692 x = 4692/34 x = 138 Length of the train is 138 m.
