Question
The cost price of article A and B is Rs. ‘X’ and Rs.
(X + 400), respectively. Article A is sold at 20% profit while article B is sold at 10% loss. If selling price of article B is Rs. 90 more than that of article A and article B is sold after giving a discount of 25%, then find the marked price of article B.Solution
Selling price of article ‘A’ = x × 120% = Rs. 1.2x Selling price of article ‘B’ = (x + 400) × 90% = Rs. 0.90x + 360 According to the question, 0.90x + 360 – 1.20x = 90 360 – 90 = 0.30x 0.30x = 270 x = 900 Selling price of article ‘B’ = 0.90 × 900 + 360 = Rs. 1170 Marked price of the article ‘B’ = 1170/75 × 100 = Rs. 1560
