Example 1: The market price of an article is $18,000. By selling it at a discount of 20% the loss is 4% find its cost price. Solution: Market price = $18,000 and discount = 20% Therefore, Selling price = M.P(100  d%) / 100 = 18,000 (100  20) / 100 = 18,000 * 80 / 100 Selling price = 14,400 Selling price = $14,400 and loss = 4% Therefore, Cost price = (Selling price * 100) / (100  l%) = (14,400 * 100) / (1004) = 1,440,000 / 96 Cost price = $15,000
