Question :

by selling a laptop for rs23,000 a dealer earns a profit of 15%.Find its cost price.

Answer :

$\sf\pink{given}$

• Selling price of a laptop is Rs 23000

• Profit percentage is 15%

$\sf\pink{to\:find}$

• Cost price of the laptop .

cost price = $\bf\purple{\dfrac{100}{100+profit\: percent}\times selling\:price}$

$\longrightarrow\bf\red{cost\:price = \dfrac{100}{100+ 15}\times 23000}$

$\longrightarrow\bf\red{cost\:price = \dfrac{100}{115}\times 23000}$

$\longrightarrow\bf\red{cost\:price = \dfrac{20}{23}\times 23000}$

$\longrightarrow\bf\red{cost\:price = 20\times 1000}$

$\longrightarrow\bf\red{cost\:price = 20000}$

• Therefore the cost price of the laptop is Rs 20,000
