Answer 2

$\sf\red{\underline{\underline{Answer:}}}$

$\sf{Cost \ price \ of \ television \ is \ Rs \ 8000.}$

$\sf\orange{Given:}$

$\sf{\implies{Profit=5\%}}$

$\sf{\implies{Cost \ price \ of \ television=Rs \ 8400}}$

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

$\sf{Cost \ price \ of \ the \ television.}$

$\sf\green{\underline{\underline{Solution:}}}$

$\sf{Let \ the \ cost \ price \ be \ Rs \ x.}$

$\sf{Profit=5\% \ of \ cost \ price}$

$\sf{Profit=\frac{5x}{100}}$

$\boxed{\sf{Selling \ price=Cost \ price+Profit}}$

$\sf{8400=x+\frac{5x}{100}}$

$\sf{8400=\frac{100x+5x}{100}}$

$\sf{8400=\frac{105x}{100}}$

$\sf{x=\frac{8400}{105}\times100}$

$\sf{x=80\times100}$

$\sf{x=8000}$

$\sf\purple{\tt{\therefore{Cost \ price \ of \ television \ is \ Rs \ 8000.}}}$
