    Train A crosses a stationary train B in 50 s and a pole in 20 s with the same speed. The length of the train A is 240 m. What is the length of the stationary train 5?

    A) 360 m

    B)        260 m

    C) 300 m

    D)        Cannot be determined

    Correct Answer: A

    Solution :

    [a] Let length of stationary train \[B=x\,m\] \[\therefore \]    \[\frac{240+x}{50}=\frac{240}{20}\] \[\Rightarrow \]            \[x=600-240=360\,\,m\]
