If the cost price of an item is 5/9 of its marked price and the profit is 20% , then the percentage of discount is = ?

Answer: Option D

let the Marked price of product = 900
∴ cost price will be = 900 × $$\frac{5}{9}$$ = 500
Profit = 20%
Selling price will be = 500 + 20% of 500 = 600
Discounted value = 900 - 600 = 300
Discount % = $$\frac{100\times 300}{900}=33\frac{1}{3}\%$$
