Answer 2

To find:

$\to$The stationers profit percentage​

Information given in the question:

• a stationary sales 8 ball point pens for the price of 10 ballpoint pens

Solution:

Let,Price of 10ball point pens be ${x}$ rs

According to the question:

The stationary sells 8ball point pens for the price of 10ball point pens,

$\to$Price of 8 ball= $x$ rs

$\to$Selling price of 1 ball point pen=$\frac{x}{8}$ rs

$\to$The cost price of 1 ball point=$\frac{x}{10}$ rs

Using formula:

Profit amount=(Selling price - Cost price)

$\to$ The profit amount of 1 pen=$\frac{x}{8} -\frac{x}{10}$ rs

                                           =$\frac{5x-4x}{40}$ rs

                                          =$\frac{x}{40}$ rs

Using formula:

Profit percentage=$\frac{Profit amount * 100}{Cost price}$

$\to$The stationers profit percentage=

                                         =($\frac{x}{40} *\frac{10}{x} *100$ )%

                                              =($\frac{1000}{40}$)%

                                               =$25$%

Answer:

The stationer's profit percentage=$25$%
