Question
A shopkeeper marked an article P% above its cost price
and sold it for Rs. 1134 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 + 20)%.Solution
Cost price of the article = (25/30) × 1134 = Rs. 945 Marked price of the article = 945/0.8 = Rs. 1417.5 P% = [(1417.5 – 945)/945] × 100 = 50% Or, P = 50 Desired selling price = 945 × 1.7 = Rs. 1606.5
