    D 2 Correct Answer Incorrect Answer

    Solution

    Solution-

    For A-

    Speed                     1         2

    Time                        2         1

    Difference time =36+42=78min

    ATQ- 1=78

    2=78×2=156min.

    Sudhansu takes time =156-36=120min = 2 hours.

    Speed =130/2=65km/h

    Sudhanshu take time =195/65=3hours.
