Question
A dishonest dealer professes to sell his goods at cost
price, but he uses a weight of 600 gm for the kg weight. Find his gain per cent.Solution
Suppose goods cost the dealer Re 1 per kg. He sells for Re 1 what cost him Re 0.6. Gain on Re 0.6 = Re 1- 0.6 = Re 0.4 Gain on Rs. 100 = 0.4 * 100/0.6 = 66.67% Gain% = 66.67% Alternate Method: Gain% = (True weight – False weight) * 100/ False weight = (1000 – 600)*100/600 = 66.67%
