The ratio of the cost price of product A to that of B is 5:7. product A was sold at a profit of 80% and product B was sold at a profit of 20%. If the total profit earned after selling both the (products A and B is Rs 296) what is the difference between the cost prices of product A and B?

1 Answer

Answer :

CP of product A= 5X

CP of product B=7x

Total price = (5x*0.8)+(7x*0.2) =296

4X+1.4X=296

5.4X=296

x=54.81=55(approx.)

difference of the CP= 7x-5x=2x=2*55

 = Rs. 110
