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

⠀⠀⠀⠀

let the CP of 1 orange be x

⠀⠀⠀⠀

CP of 36 oranges = 36x

⠀⠀⠀⠀

let the SP of 1 orange be y

⠀⠀⠀⠀

SP of 36 oranges = 36y

⠀⠀⠀⠀

• ATQ :- Loss = SP of 4 oranges

⠀⠀⠀⠀

Loss = 4y --- ( i )

⠀⠀⠀⠀

$\sf{\red{\boxed{\bold{Loss = CP - SP}}}}$

⠀⠀⠀⠀

Loss = 36x - 36y

⠀⠀

From eq ( i )

⠀⠀⠀⠀

4y = 36x - 36y

⠀⠀⠀⠀

36x = 40y

⠀⠀⠀⠀

x = 40y / 36

⠀⠀⠀⠀

x = 20y / 18

⠀⠀⠀⠀

x = 10y / 9 ----- ( ii )

⠀⠀⠀⠀

$\sf{\red{\boxed{\bold{Loss\% = \dfrac{loss}{CP}\times 100}}}}$

⠀⠀⠀⠀

$\sf: \implies\: {\bold{ Loss\% = \dfrac{4y}{36x}\times 100}}$

⠀⠀⠀⠀

• From eq ( ii )

⠀⠀

$\sf: \implies\: {\bold{ Loss\% = \dfrac{4y}{36\times\dfrac{10y}{9}}\times 100}}$⠀⠀

⠀⠀⠀⠀

$\sf: \implies\: {\bold{ Loss\% = \dfrac{4y}{4y\times 10}\times 100}}$

⠀⠀⠀⠀

$\sf: \implies\: {\bold{ Loss\% = \dfrac{100}{10}}}$

⠀

$\sf: \implies\: {\bold{ Loss\% = 10\%}}$
