    A) 216       

    B)        220

    C) 210                     

    D)       230

    E)  None of these

    Solution :

    Explanation Option [a] is correct. Let the power of the terms be x and y. \[{{6}^{x}}-{{11}^{y}}=95\] Put \[x=3,\text{ }y=2\] (By trial and error) \[{{6}^{3}}-{{11}^{2}}=95\] Hence satisfied Score of team A = 63 = 216
