Question
The cost price of article A and B is Rs. ‘X’ and Rs.
(X + 500), 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 20%, 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 + 500) × 90% = Rs. 0.90x + 450 According to the question, 0.90x + 450 – 1.20x = 90 450 – 90 = 0.30x 0.30x = 360 x = 1200 Selling price of article ‘B’ = 0.90 × 1200 + 450 = Rs. 1530 Marked price of the article ‘B’ = 1530/85 × 100 = Rs. 1800
