Question

trader sold an article at a profit of 20%.if he had bought that article at Rs.30.less and sold it at the

same selling price,he would have made a profit of 40%.what is the selling price of the article?​

Answer 1

Step-by-step explanation:

Let cost be 100x

Sold at 20% profit , sale price = 120x

New cost = 60% less = 40x

New sale price = 120x-90

Profit = 120x-90 -40x = 80x-90

( 80x-90) /40x = 50/100=1/2

160x -180 = 40x

120x = 180

x = 1.5

100x = Rs 150
