Answer 1

$\sf{\bold{\purple{\star{\underline{\underline{Given}}}}}}$

⠀⠀⠀⠀

Selling price of article = Rs. 42

Loss % = 30%

⠀⠀

$\sf{\bold{\purple{\star{\underline{\underline{To\: find }}}}}}$

⠀⠀⠀⠀

cost price of article = ??

⠀⠀⠀⠀

$\sf{\bold{\purple{\star{\underline{\underline{Solution}}}}}}$

⠀⠀

let the CP be x

⠀⠀⠀⠀

$\sf{\bold{\orange{\star{\underline{\underline{Loss = CP - SP}}}}}}$

⠀⠀⠀⠀

Loss = x - 42

⠀⠀⠀⠀

$\sf{\bold{\orange{\star{\underline{\underline{Loss\% = \dfrac{loss}{CP}\times 100}}}}}}$

⠀⠀⠀⠀

$\sf:\implies \: {\bold{ 30 = \dfrac{x - 42}{x}\times 100 }}$

⠀⠀⠀⠀

$\sf:\implies \: {\bold{ 30x = ( x - 42 ) \times 100 }}$

⠀⠀⠀⠀

$\sf:\implies \: {\bold{ 30x = 100x - 4200}}$

⠀⠀⠀⠀

$\sf:\implies \: {\bold{ 30x + 4200 = 100x}}$

⠀⠀⠀⠀

$\sf:\implies \: {\bold{ 4200 = 100x - 30x }}$

⠀⠀⠀⠀

$\sf:\implies \: {\bold{ 4200 = 70x }}$

⠀⠀⠀⠀

$\sf:\implies \: {\bold{ x = \dfrac{4200}{70} }}$

⠀⠀⠀⠀

$\sf:\implies \: {\bold{ x = \dfrac{420}{7} }}$

⠀⠀⠀⠀

$\sf:\implies \: {\bold{ x = Rs. 60 }}$

⠀⠀⠀⠀

⠀⠀⠀⠀
