    The length of a train and that of a platform are equal. If with a speed of 90 km/h, the train crosses the platform in 1 min, then the length of the train (in m) is

    A) 500                              

    B) 600

    C) 750                  

    D) 900

    Correct Answer: C

    Solution :

    Let the length of a train = x m \[\therefore \]      Length of platform = x m \[\therefore \]      \[\frac{90\times 5}{18}=\frac{x+x}{60}\] \[\Rightarrow \]   \[2x=25\times 60\]                  = 1500 \[\Rightarrow \]   \[x=750\,m\]
