Explanation: Type a তে Milk: Fruit juice = 4:3 পরিমান ধরে নিই, 4x এবং 3x type B তে Milk : Fruit juice = 3:4 এখন , \(4x+3x=14 \Rightarrow x=2\) অর্থাৎ Milk = 8, F.J = 6 ধরি, y lit F.J add করতে হবে, অর্থাৎ \(8:6+y=3:4 \Rightarrow \frac{8}{6+y}=\frac{3}{4} \Rightarrow 3y=14 \Rightarrow y=4\frac{2}{3}\)
