How do you calculate the vapor pressure of benzene?

Vapour pressure of a mixture of benzene and toluene is given by $P = 179{X_B} + 92$, where ${X_B}$ is the mole fraction of benzene. If vapours are removed and condensed into liquid then what will be the ratio of mole fraction of benzene and toluene in first condensate.
