Question
A shopkeeper bought two article A&B for a total of
rupees 3500. He marked Article A 140% above its cost price and sold it after giving a discount of 20% while he sold Article B at loss of 28%. If selling price of article A Rs. 252 more than that of article B, then find a difference between cost price of article A and B.Solution
Let cost price of article A is Rupees X. So cost price of Article B = Rs. (3500-x) Selling price of Article A = 0.80*2.4*x=1.92x Selling price of Article B = 0.72*(3500-x)= rs. (2520-0.72x). So 1.92x = 2520-0.72x+252 X=1050 Cost Price of Article A = rs. 1050 Cost Price of Article B = 3500-1050 = Rs. 2450 Desired difference = 2450-1050 Â Rs. 1400
