Question
The cost price of article A and B is Rs. ‘X’
and Rs. (X + 550), 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 10%, 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 + 550) × 90% = Rs. 0.90x + 495 According to the question, 0.90x + 495 – 1.2x = 90 495 – 90 = 0.3x 0.3x = 405 x = 1350 Selling price of article ‘B’ = 0.90 × 1350 + 495 = Rs. 1710 Marked price of the article ‘B’ = 1710/90 × 100 = Rs. 1900
