  • Question
  • The banker's discount on Rs. 1650 due a certain time hence is Rs. 165. Find the true discount and the banker's gain.


  • Options
  • A. 15
  • B. 20
  • C. 18
  • D. 13

  • Correct Answer
  • 15 

    Explanation

       Sum = [(B.D.xT.D.)/ (B.D.-T.D.)]

                  = [(B.D.xT.D.)/B.G.]

    T.D./B.G.  = Sum/ B.D.

       =1650/165

                   =10

    Thus, if B.G. is Re 1, T.D. = Rs. 10.

    If B.D.is Rs. ll, T.D.=Rs. 10.

    If B.D. is Rs. 165, T.D. = Rs. [(10/11)xl65]

                =Rs.150

     And, B.G. = Rs. (165 - 150) = Rs, 15.
