  1. A trader sells 20 kg of sugar at Rs. 400. A customer asks 20% discount and he agrees to it but instead of 1 kg he gives 4% less sugar. what is the effective discount that the customer gets ?
    1. 16 %
    2. 16.66 %
    3. 15.5 %
    4. 19.6 %
  1. Correct Option: B

    Let the MP = Re. 1 per kg then
    Initially :
    Weight = 100 kg
    MP = Rs. 100
    Rate = 1 Rs / kg.

    Finally :
    Weight = 96 kg
    MP = Rs. 96
    Rate = 80 / SP = 80/96

    Effective discount = 1- 80 / 96 = 16 / 96
    % discount = [(16 / 96) ]x 100 = 16.66 %
