Marked price = Rs 650 and Discount percentage = 2.5%. find selling price

levacccp [35]

Answer:

The selling price is <u>Rs.633.75</u>.

<h3><u>Solution</u> :</h3>

Here we have given that :

$\pink\star$ Marked Price = Rs.650
$\pink\star$ Discount % = 2.5 %

We need to find the selling price.

Firstly, finding the discount by substituting the values in the formula :

${\longrightarrow{\sf{Discount = Marked \: Price \times Discount \%}}}$

${\longrightarrow{\sf{Discount =650\times 2.5\%}}}$

${\longrightarrow{\sf{Discount =650\times \dfrac{2.5}{100}}}}$

${\longrightarrow{\sf{Discount = \dfrac{650 \times 2.5}{100}}}}$

${\longrightarrow{\sf{Discount = \dfrac{1625}{100}}}}$

${\longrightarrow{\sf{Discount = 16.25}}}$

Hence, the discount is Rs.16.25.

$\rule{200}2$

Now, finding the selling price by substituting the values in the formula :

${\longrightarrow{\sf{Selling \: Price = Marked \: Price - Discount}}}$

${\longrightarrow{\sf{Selling \: Price = 650 - 16.25}}}$

${\longrightarrow{\sf{Selling \: Price =633.75}}}$

Hence, the selling price is Rs.633.75.

$\rule{300}{2.5}$

First multiply the equation by 5 to get y by itself.
$y+35=120$
Then subtract 35 from each side to get the integer by itself.
So, final answer:
