Question :

Juhi sells a washing machine for 13,500. She loses 20% in the bargain. What was

the price at which she bought it?

Answer :

$\sf\pink{Given:}$

• selling price is 13500.

• she losses 20% in bargain .

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

• cost price ?

Explanation :

• let the price be "x"

$\\ \longrightarrow\sf{x - \dfrac{20}{100}\times x = 13500}$

$\\ \longrightarrow\sf{x - \dfrac{20x}{100}= 13500}$

$\\ \longrightarrow\sf{\dfrac{100x}{100}- \dfrac{20x}{100} = 13500}$

$\\ \longrightarrow\sf{\dfrac{100x - 20x}{100} = 13500}$

$\\ \longrightarrow\sf{\dfrac{80x}{100} = 13500}$

$\\ \longrightarrow\sf{80x = 13500\times 100}$

$\\ \longrightarrow\sf{80x = 1350000}$

$\\ \longrightarrow\sf{x = \dfrac{1350000}{80}}$

$\\ \longrightarrow\sf{x = \dfrac{135000}{8}}$

$\\ \longrightarrow\sf{x = 16875}$

• Therefore she bought it for Rs 16875 .
