    A train passes a man standing on a platform in 8 s and also crosses the platform which is 264 m long in 20 s. The length (in m) of the train is

    A) 188      

    B)  176    

    C)  175     

    D)  96

    Correct Answer: B

    Solution :

    Let the length of train = x m When the train crosses man, Speed \[=\frac{x}{8}\] When the train crosses platform, Speed \[=\frac{x+264}{40}\] \[\therefore \]      \[\frac{x}{8}=\frac{x+264}{20}\] \[\Rightarrow \]   \[20x=8x+2112\] \[12x=2112\]\[\Rightarrow \]\[x=\frac{2112}{12}=176\,\,\text{m}\]
