X and Y are 25% and 40% higher than their cost prices, respectively. After a 10% discount on both items, X sells for Rs. 225 and Y sells for Rs. 378. What is the combined cost price of X and Y?Solution
Let the cost price of article X = 100a Cost price of article Y = 100b MRP of article X = 125a MRP of article Y = 140b According to question- 90% of 125a = 225 a = 225/125 × 100/90 a = 2 100a = 200 90% of 140b = 378 b = 378/140 × 100/90 b = 3 100b = 300 cost price of both the articles = 100a+100b = 200+300 = 500
