Question
A dishonest dealer claims to sell goods at cost price
but uses a false weight of 900g instead of 1kg. What is his profit percentage?Solution
Let the cost price of 1kg be 100. The dealer sells 900g for 100, so his effective cost for 900g is 100 × 900/1000 = 90 Profit = 100 - 90 = 10 Profit percentage = 10/90 × 100 ~ 11.11%
