Question
A trader advertises to sell sugar at a profit of 25% but
cheats by using a weight that measures only 800 gm instead of 1 kg. What is the actual profit percentage the trader makes?Solution
ATQ,
Let the cost price of 1 gm sugar be Rs. 'n'. So, cost price of 1 kg sugar = 1000 X n = Rs. '1000n' Or, cost price of 800 gm sugar = 800 X n = Rs. '800n' Selling price of 1 kg sugar = 1.25 X 1000n = Rs. '1250n' Profit earned = 1250n - 800n = Rs. '450n' Required profit percentage = (450n / 800n) X 100 = 56.25%
