Answer» Correct Answer - Option 3 : 15.4% Given: Selling price of article = 575 Marked price of article = 850 Successive discounts = 20% and X% Formula used: S.P = markup – discount Percent discount = discount/M.P × 100 Calculation: M.P of article = 850 Value of article after discount of 20% = 850 – 20% of 850 = 850 – 170 = 680 Now, new marked price of an article = 680 ⇒ S.P = 575 Discount = 680 – 575 = 105 Discount% = 105/680 × 100 = 15.4% ∴ The value of X is 15.4%. |
