Answer 2

$\huge \fbox{Answer}$

$\large \underline{\underline{ \frak{ \color{red}Given::}}}$

$\mapsto \sf{Cost \: price \: of \: article = ₹250}$

$\mapsto \sf{Selling \: price \: of \: article=₹300}$

$\large \underline{\underline{ \frak{ \color{blue}Concept \: used::}}}$

${ \leadsto{\sf{If \: selling \: price > cost \: price \: then \: profit \: is \: found.}}}$

$\large \underline{\underline{ \frak{ \color{green}Formula \: required::}}}$

$\pink \star{ \fbox{Profit=Selling price-Cost price}} \pink \star$

$\pink \star{ \boxed {\rm{Profit\%= \frac{Profit}{Cost \: price} \times 100 }}} \pink \star$

$\large \underline{\underline{ \frak{ \color{indigo}According \: to \: Question::}}}$

$\sf{ \implies{Profit=Selling \: price-Cost \: price}}$

$\sf{ \implies{Profit=₹300 - ₹250}}$

$\sf{ \implies{Profit=₹50}}$

${ \bf {{Then, }}}$

$\sf{ \implies {\sf{Profit \: \%= \frac{Profit}{Cost \: price} \times 100 }}}$

$\sf{ \implies {\sf{Profit \: \%= \frac{₹50}{₹250} \times 100 }}}$

$\sf{ \implies {\sf{Profit \: \%= \frac{₹50}{₹25 \cancel0} \times 10 \cancel0 }}}$

$\sf{ \implies {\sf{Profit \: \%= \cancel\frac{₹50}{₹25} \times 10 }}}$

$\sf{ \implies {\sf{Profit \: \%= 2 \times 10 }}}$

$\sf{ \implies {\sf{Profit \: \%= 20 \% }}}$

$\bf{Hence, }$

$\pink \star{ \boxed {\rm{Profit\% \: or \: Gain\% = 20\% }}} \pink \star$
