a shopkeeper purchased a TV at ₹15,000 and gives a discount of 20% on its marked prize and still got a profit of 8% . find the m
Setler79 [48]

\huge\sf\underline{Answer}

\sf\longrightarrow selling \: prize \:   =  \frac{100 + profit\%}{100}  \times cp

\sf\longrightarrow  \frac{108}{100}  \times 15000 = 16200

Let the marked prize of the TV be x .

\sf\longrightarrow discount = 20\% \: of \: x \:  =  \frac{20}{100}x =  \frac{x}{5}

We have SP = MP - Discount

\sf\longrightarrow 16200 \:  =  \: x -  \frac{x}{5}

\sf\longrightarrow 16200 \:  =  \frac{4x}{5}

\sf\longrightarrow x \:  =  \: 20250

<em>Hence </em><em>,</em><em> </em><em>T</em><em>he </em><em>marked</em><em> </em><em>prize</em><em> </em><em>of </em><em>the </em><em>TV </em><em>is </em><em>₹</em><em>2</em><em>0</em><em>,</em><em>2</em><em>5</em><em>0</em><em> </em><em>.</em>

<em>Hope </em><em>it </em><em>helps </em><em>~</em><em> </em>
