Answer 1

Answer:

profit=25%

Hope it helps you!!

Step-by-step explanation:

cost price of the article =₹80

selling price of the article=₹100

profit =S.P - C.P

=₹100-₹80

=₹20

profit%= (₹20/₹80×100)%

= 25%

Answer 2

$\begin{gathered}\begin{gathered}\bf Given -  \begin{cases} &\sf{Cost \: Price \: = \: Rs \: 80} \\ &\sf{Selling \: Price \: = \: Rs \: 100 } \end{cases}\end{gathered}\end{gathered}$

$\begin{gathered}\begin{gathered}\bf  To \:  Find :-  \begin{cases} &\sf{Profit \: \% \: or \: Loss \: \%}  \end{cases}\end{gathered}\end{gathered}$

$\large\underline\purple{\bold{Solution :- }}$

Here,

It is given that

• Cost Price of an Article = Rs 80

• Selling Price of an Article = Rs 100

Since, Selling Price > Cost Price

• So, there is Profit in this transaction.

Now, we know

$\bigstar \boxed{ \green{ \rm \: Profit \: = \: Selling \: Price - \: Cost \: Price}}$

$\rm : \implies \: Profit \: = \: 100 \: - \: 80$

$\rm : \implies \:Profit \: = \: Rs \: 20$

Now,

$\bigstar \boxed{ \pink{ \rm \: Profit \: \% \: = \dfrac{Profit}{Cost \: Price} \times 100 \: \%}}$

$\rm : \implies \:Profit \: \% \: = \dfrac{20}{80} \times 100 \: \%$

$\rm : \implies \:Profit \: \% \: = 25 \: \%$
