Answer 2

Answer:

Profit percentage = 20%

Step-by-step explanation:

Given data

Leonard brought an earphone at four-fifth of its marked price  

and sold it 20% above the marked price

here we need to find profit percentage that Leonard gained

Let x be the marked price

then the cost price that Leonard brought = $\frac{4}{5} (x)$ = $\frac{4x}{5}$  

Leonard sold it 20%  above the marked price

⇒ selling price = $\frac{20}{100} (x)$ + x = $\frac{x}{5} + x$  = $\frac{x+ 5x }{5}$ = $\frac{6x}{5}$  

⇒ profit = $\frac{6x}{5} - x$ = $\frac{6x -5x}{5}$  = $\frac{x}{5}$      

⇒ profit percentage = $\frac{\frac{x}{5} }{x} (100)$ = $\frac{x}{5} (\frac{1}{x} )(100)$ = 20%
