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

⠀⠀⠀⠀

Marks rupa gets = 185

⠀⠀⠀⠀

Passing marks = marks obtained + fails by

⠀⠀⠀⠀

Passing marks = 185 + 15

⠀⠀⠀⠀

Passing marks = 200

⠀⠀⠀⠀

Passing percentage = 40%

⠀⠀⠀⠀

• Let total marks be x

⠀⠀

ATQ :-

⠀⠀⠀⠀

$\sf: \implies\: {\bold{ 40\% of x = 200}}$

⠀⠀⠀⠀

$\sf: \implies\: {\bold{ \dfrac{40}{100}\times x = 200}}$

⠀⠀⠀⠀

$\sf: \implies\: {\bold{ \dfrac{4x}{10}= 200 }}$

⠀⠀⠀⠀

$\sf: \implies\: {\bold{ x = \dfrac{200\times 10}{4}}}$

⠀⠀⠀⠀

$\sf: \implies\: {\bold{ x = \dfrac{100\times 10}{2}}}$

⠀⠀⠀⠀

$\sf: \implies\: {\bold{ x = {50\times 10}}}$

⠀⠀⠀⠀

$\sf: \implies\: {\bold{ x = 500 }}$
