Dear Student,

Please find below the solution to the asked query:
$$\begin{gathered} \mathrm{Let} \mathrm{y} \mathrm{eggs} \mathrm{she} \mathrm{needed} \mathrm{for} 12 \mathrm{dozen} \mathrm{cookies} \\ \Rightarrow 3 \mathrm{dozen} \mathrm{called} \mathrm{for} 4\mathrm{eggs} \\ \mathrm{So} \\ \Rightarrow 12 : 3 :: \mathrm{y} :4 \\ \Rightarrow \frac{12}{3}=\frac{\mathrm{y}}{4} \\ \Rightarrow \mathrm{y}=\frac{12\times 4}{3}=\frac{48}{3}=16 \\ \mathrm{So} \mathrm{she} \mathrm{needed} 16 \mathrm{eggs} \mathrm{for} 12 \mathrm{dozen} \mathrm{cookies} \end{gathered}$$
