  • 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. Rs. 150, Rs. 15
  • B. Rs. 160, Rs. 5
  • C. Rs. 145, Rs. 20
  • D. None of these

  • Correct Answer
  • Rs. 150, Rs. 15 

    Explanation

    Sum = (B.D. x T.D.) / (B.D. - T.D.) = (B.D. x T.D.) / B.G.
    ? T.D. / B.G. = Sum / B.D. = 1650/165 = 10/1
    i.e., if B.G. is Re. 1, T.D. = Rs. 10 or B.D. = Rs. 11
    ? if B.D. is Rs. 11, T.D. = Rs. 10
    If B.D. is Rs. 165, T.D. = Rs. (10/11) x 165 = Rs. 150
    Also, BG = Rs. (165 - 150) = Rs. 15
