The ratio of selling price to the cost price is 21 : 16. What is the profit percentage?
Ratio of selling price to the cost price = 21 : 16
Let Cost price = $$x=16$$ and selling price = $$y=21$$
=> Profit % = $$\frac{(y-x)}{x}\times100$$
= $$\frac{(21-16)}{16}\times100$$
= $$\frac{500}{16}=31.25\%$$
=> Ans - (D)
