\((5x-3y):(2x+4y)=11:12\) হলে, \(x:y\) নির্ণয় করি ।


\((5x - 3y) : (2x + 4y) = 11:12\)
বা, \(\cfrac{5x-3y}{2x+4y}=\cfrac{11}{12} \)
বা, \(60x-36y=22x+44y \)
বা, \(60x-22x=44y+36y \)
বা, \(38x=80y \)
বা, \(\cfrac{x}{y}=\cfrac{80}{38} \)
বা, \(\cfrac{x}{y}=\cfrac{40}{19} \)
বা, \(x:y=40:19\)

\(∴x:y=40:19 \) (Answer)
