    Answer : Option A

    Explanation :

    Let the length of each train be x metres.

     

    Then, distance covered = 2x metres.

     

    Relative speed = (46 - 36) km/hr

       =   [10∗518]   m/sec
     
       = [259]   m/sec
     
      2X36=259   
       

     2x = 100

     x = 50.
