Question 16b

Dear Student,

$$\begin{gathered} \mathrm{A}\text{'}\mathrm{s} \mathrm{sacrifice} \mathrm{in} \mathrm{favour} \mathrm{of} \mathrm{C}=\frac{5}{8}\times \frac{1}{2}=\frac{5}{16} \\ \mathrm{A}\text{'}\mathrm{s} \mathrm{new} \mathrm{share}=\frac{5}{8}-\frac{5}{16}=\frac{5}{16} \\ \mathrm{B}\text{'}\mathrm{s} \mathrm{sacrifice} \mathrm{in} \mathrm{favour} \mathrm{of} \mathrm{D}=\frac{3}{8}-\frac{1}{4}=\frac{1}{8} \\ \mathrm{B}\text{'}\mathrm{s} \mathrm{new} \mathrm{share}=\frac{3}{8}-\frac{1}{8}=\frac{2}{8} \\ \mathrm{C}\text{'}\mathrm{s} \mathrm{share}=\frac{5}{16} \\ \mathrm{D}\text{'}\mathrm{s} \mathrm{share}=\frac{1}{8} \\ \mathrm{New} \mathrm{Ratio}=\frac{5}{16}:\frac{2}{8}:\frac{5}{16}:\frac{1}{8} \mathrm{or} 5:4:5:2 \end{gathered}$$
