Question
The ratio of the cost price to the marked price of an
article is 2:5 and the ratio of the profit percentage to the discount percentage is 5:2. Find the profit percentage.Solution
CP:MP = 2x:5x Profit = MP – CP = 5x – 2x = 3x Profit% : Discount% = 5:2 Let CP = 200 and SP = (2x + 5x = 5x) = 500 According to question, => (5x/100) × 200 + (2x/100) × 500 => 10x + 10x = 20x => 20x ----100 => x = 5% Profit % = 5 × 5% = 25%
