Answer: 44%
Step-by-step explanation: let the dealer wanted to buy 100 kg from the seller . But his forged weights will allow him to gain 20 % extra , that is 100 * 120/100 = 120 kg .
When that dealer will sell the same thing to a buyer then the item of 120 kg will appear 20 % greater to the buyer, that is 120 * 120/100 = 144 kg.
So he is selling 144 kg , while he tricked the seller of purchasing 100 kg . From here we got the profit is 144 - 100 = 44 kg .
True gain percentage 44% .
