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%.
