Let the marked price of the article be 10a According to the question, 10a - 10a × 10% = 720 ⇒ 9a = 720 ⇒ a = 720/9 = 80 So, the marked price of the chair = 10 × 80 ⇒ Rs. 800 Now, Profit on the chair when it is sold at marked price = 800 - 640 ⇒ Rs. 160 Profit % = (160/640) × 100 ⇒ 25 ∴ The profit percentage will be 25%
