The marked price of an article is $\frac{7}{5}$ of the cost price. If discount of 20% is given on the marked price, then what is the profit percentage?

12%

The marked price of an article = $\frac{7}{5}$ of the cost price

\(\frac{MP}{CP}\) = \(\frac{7}{5}\)

Discount = 20%

Discount of 20% means selling price is 80% of the Marked price

Selling price = 80% of 7 = 5.6

Profit = 5.6 - 5 = 0.6

Profit% = 0.6 × \(\frac{100}{5}\)  =  12%
