Answer 1

$\textbf {Hey there, here is the solution.}$

.............................................................................................

Let the cost price of 1 article = x

Find the cost price of the 15 articles:

15 articles = 15x

Find the selling price of the 15 articles:

15 articles = 12x

Find the profit/loss:

Since the selling price is less than the cost price

⇒ It is a loss

Loss = 15x - 12x = 3x

Find the loss percentage:

Loss percentage = 3x/15x x 100 = 20%

Answer: He made a loss of 20%

Answer 2

Hello!!!!

Here is your answer!!!....

Solution. -

S.P. of 15 articles =C. P. of 12.articles - - -(1.)


Let the cost of 1 article =x

From 1 St equation we clearly know that it is case of loss {C. P. >S. P.}

LOSS =15x - 12x = 3x

Loss percentage formula
$\frac{loss}{c.p.} \times 100 \\ \\ \frac{3x}{15x} \times 100 \\ \\ \frac{100}{5} \\ \\ 20$
So,
Loss percentage =20%
