An article with cost price of Rs. 1600 is marked 44%
above its cost price and sold after two successive discounts of 13% and Rs. ‘X’ respectively such that it is sold at a profit of 20%. Find the value of ‘X’.Solution
Marked price of the article = 1600 × 1.44 = Rs. 2304 Selling price of the article after first discount = 2304 × (87/100) = Rs. 2004.48 Selling price of the article after second discount = 1600 × 1.2 = Rs. 1920 So, second discount = X = 2004.48 – 1920 = 84.48
