Question
A shopkeeper marked an article P% above its cost price
and sold it for Rs. 2160 after giving a discount of 20%. If the ratio of cost price and selling price of the article is 25:30, respectively, then find the selling price if the article is sold at a profit of (P + 25)%.Solution
Cost price of the article = (25/30) × 2160 = Rs. 1800 Marked price of the article = 2160/0.8 = Rs. 2700 P% = [(2700 – 1800)/1800] × 100 = 50% Or, P = 50 Desired selling price = 1800 × 1.75 = Rs. 3150
