$\frac{{\mathrm{x}}_{\mathrm{A}}{\mathrm{P}}_A^o}{{\mathrm{x}}_B{\mathrm{P}}_B^o}=\frac{{\mathrm{y}}_A}{{\mathrm{y}}_B}$

(A) $\frac{{\mathrm{y}}_{\mathrm{A}}}{{\mathrm{y}}_{\mathrm{B}}}=\frac{1}{1}\times \frac{120}{160}=\frac{3}{4}$

(B) $\frac{{\mathrm{y}}_{\mathrm{A}}}{{\mathrm{y}}_{\mathrm{B}}}=\frac{1}{3}\times \frac{120}{160}=\frac{1}{4}$

(C) $\frac{{\mathrm{y}}_{\mathrm{A}}}{{\mathrm{y}}_{\mathrm{B}}}=\frac{3}{1}\times \frac{120}{160}=\frac{9}{4}$

(D) $\frac{{\mathrm{y}}_{\mathrm{A}}}{{\mathrm{y}}_{\mathrm{B}}}=\frac{5}{1}\times \frac{120}{160}=\frac{15}{4}$
