Question

• The cost price of 60 articles is equal to selling price of 80 articles, then find profit or loss percent in this transaction.​

Answer 1

$\clubsuit \: \rm \underline{\underline{Solution}}$

✰ Information mentioned in the question :

$\rm \implies \: The \: C.P \: of \: 60 \: articles = The \: S.P \: of \: 80 \: articles \:$

$\rm \implies \: 60 \times C.P = S.P \times 80$

$\rm \implies \: \dfrac{C.P}{S.P} = \dfrac{80}{60}$

$\rm \implies \: \dfrac{C.P}{S.P} = \dfrac{80 \div 2}{60 \div 2}$

$\rm \implies \: \dfrac{C.P}{S.P} = \dfrac{40}{30}$

$\rm \mapsto \: As \: C.P > S.P , Loss \: is \: made$

✰Formula used ༄

$\clubsuit \: \rm \: Loss \: percent$

$\longrightarrow\bigstar \: \: \sf\boxed{\bold{\orange{ \dfrac{C.P - S.P}{S.P} \times 100\%}}}\: \: \: \bigstar$

✰Now ༄

➡ Substitute the given values in above formula and solve

$\longrightarrow\bigstar \: \: \sf\boxed{\bold{\blue{ \dfrac{40 - 30}{40} \times 100\%}}}\: \: \: \bigstar$

$\longrightarrow\bigstar \: \: \sf\boxed{\bold{\pink{ \dfrac{10}{40} \times 100\%}}}\: \: \: \bigstar$

$\longrightarrow\bigstar \: \: \sf\boxed{\bold{\red{ \dfrac{1000}{40}}}} \: \: \bigstar$

$\longrightarrow\bigstar \: \: \sf\boxed{\bold{\purple{{25 \: \%}}}} \: \: \bigstar$

✰Therefore ༄

• ➡ The required required loss percent is 25 %
