 \underline {\green{\bf Given :-}}

 \implies \sf x \: : \: y \:  = 2 \: : \: 3

 \underline {\green{\bf To \ find :-}}

 \implies \sf \: (3x \:  +  \: 2y) \: : \: (2x \:  +  \: 5y)

 \underline {\green{\bf Solution :-}}

⇒ x/y = 2/3

⇒ x = 2y/3

⇒ ( 3 x + 2 y) : (2 x + 5y)

⇒ ( 3 × 2y/3 + 2y) : (2 × 2y/3 + 5y)

⇒ ( 2 y + 2 y) : (4 y / 3 + 5 y)

⇒ 4 y : ( 4y + 15 y / 3)

⇒ 4 y : 19 y / 3

⇒ 4 y ÷ 19 y / 3

⇒ 4 y × 3 / 19y

⇒ 12 / 19

12 : 19

\sf\green{Hence, \ 12:19 \ is \ the \ answer. }

\pink{\bold{\underline{\underline{Given :}}}}

⟶ x : y = 2 : 3

_______________________

\pink{\bold{\underline{\underline{To \ Find :}}}}

⟶ ( 3x + 2y ) : ( 2x + 5y )

_______________________

\pink{\bold{\underline{\underline{Solution:-}}}}

⇒( 2x + 3y ) : ( 3x + 5y )

⇒( 2 × \frac{3y}{2} + 3y ) : ( 3 × \frac{3y}{2} + 5y )

⇒( \frac{6y}{2} + 3y ) : ( \frac{9y}{2} + 5y )

⇒( \frac{6y + 6y}{2} ) : ( \frac{9y + 10y}{2}

\frac{12y}{2} : \frac{19y}{2}

\frac{12y}{2} ÷ \frac{19y}{2}

\frac{12y}{2} × \frac{2}{19y}

\frac{12}{19}

⇒12 : 19

\sf\orange{Hence \ answer \ is  \ 12 : 19}
