Question
The ratio between the cost price of article A and B is
9:8 respectively. Each of the articles was marked 40% above its cost price. If the MRP of article A is Rs. 2800 more than the MRP of article B, then find out the sum of the cost price of both of the articles.Solution
The ratio between the cost price of article A and B is 9:8 respectively. Let’s assume the cost price of article A and B is 9y and 8y respectively. Each of the articles was marked 40% above its cost price. If the MRP of article A is Rs. 2800 more than the MRP of article B. 9y of (100+40)% = 8y of (100+40)% + 2800 9y of 140% = 8y of 140% + 2800 9y x 1.4 = 8y x 1.4 + 2800 1.4(9y - 8y) = 2800 y x 1.4 = 2800 y = 2000 Sum of the cost price of both of the articles = 9y+8y = 17y = 17x2000 = Rs. 34000
