Answer 1

Pawni bought a music CD for 125 and sold it to her friend for 150 . Calculate her profit or loss percent.

➤ Given :-

Cost price of a CD :- ₹ 125

Selling price of a CD :- ₹ 150

➤ To Find :-

Profit percentage of the given sum………

➤ Formula required :-

$\large \tt \dashrightarrow \orange{ \boxed{ \tt \gray{ \dfrac{Profit}{Cost \: price} \times 100}}}$

➤ Solution :-

Profit :-

$\tt \longrightarrow150 - 125$

$\tt \longrightarrow \sf Rs \: \: \tt 25$

Now,

Profit percentage :-

$\tt \longrightarrow \dfrac{25}{125} \times 100$

$\tt \longrightarrow \dfrac{25}{ \cancel{125}} \times \cancel{100} = \boxed{ \tt \dfrac{25}{5} \times 4}$

$\tt\longrightarrow \dfrac{25 \times 4}{5} = \dfrac{100}{4}$

$\tt \longrightarrow \cancel \dfrac{100}{4} = 25 \bf\%$

$\Huge\therefore$The profit percentage of the given sum is 25 $\bf\%$.

$\tt \longrightarrow \dfrac{90}{ \cancel{335}} \times \cancel{100} = \boxed{ \tt \dfrac{90}{67} \times 20}$

$\tt \longrightarrow \dfrac{90 \times 20}{67} = \dfrac{1800}{67}$
