Question

Cp=12000 ( cost price )
Loss% = 20%
Find the sp (selling price)

Answer 1

Answer:

Given cost price is Rs.1200

loss is 25%

loss =1200×

100

25

=300

so selling price =1200−300

=900

∴ selling price is Rs.900

Hope this help

Answer 2

Answer:

The selling price is Rs. 9600.

Step-by-step-explanation:

We have given that,

Cost price ( CP ) = Rs. 12000

Loss % = 20

We have to find selling price ( SP ).

Now, we know that,

$\displaystyle{\pink{\sf\:Loss\:\%\:=\:\dfrac{Loss}{Cost\:price}\:\times\:100}}$

$\displaystyle{\implies\sf\:20\:=\:\dfrac{CP\:-\:SP}{CP}\:\times\:100}$

$\displaystyle{\implies\sf\:20\:=\:\dfrac{(\:CP\:-\:SP\:)\:\times\:100}{CP}}$

$\displaystyle{\implies\sf\:20\:\times\:CP\:=\:100\:CP\:-\:100\:SP}$

$\displaystyle{\implies\sf\:100\:SP\:=\:100\:CP\:-\:20\:CP}$

$\displaystyle{\implies\sf\:100\:SP\:=\:80\:CP}$

$\displaystyle{\implies\sf\:SP\:=\:\dfrac{80\:CP}{100}}$

$\displaystyle{\implies\sf\:SP\:=\:\dfrac{80\:\times\:120\cancel{00}}{1\cancel{00}}}$

$\displaystyle{\implies\sf\:SP\:=\:80\:\times\:120}$

$\displaystyle{\implies\sf\:SP\:=\:9600}$

$\displaystyle{\implies\underline{\boxed{\red{\sf\:Selling\:price\:=\:Rs.\:9600\:}}}}$

∴ The selling price is Rs. 9600.
