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?
Correct Answer: 16.66 %
Explanation:
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 %
