Question
The cost price of article A and B is Rs. X and Rs. (X +
600), respectively. Article A is sold at 20% profit while article B is sold at 10% loss. If selling price of article B is Rs. 120 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 + 600) x 90% = Rs. 0.90x + 540 According to the question, 0.90x + 540 - 1.20x = 120 540 - 120 = 0.30x 0.30x = 420 x = 1400 Selling price of article B = 0.90 x 1400 + 540 = Rs. 1800 Marked price of the article B = 1800/90 x 100 = Rs. 2000
