Question

products a and b were sold at the profit of 25% and 15% respectively and the total selling price is 1690. if they were sold at 20% and 30% the total selling price would have been 1740. find the difference between cost price of two products ​

Answer 1

Answer

x and y be the actual price of A and B.

Now if the profit after selling A and B is 25% and 15%

Then selling price is 1.25x and 1.15y

And 1.25x+1.15y= 1690

Also if the profit is 20% and 30%

Then selling price is 1.2x and 1.3y

Hence 1.2x+1.3y=1740

x-y=1690-24*1740/25=19.6
