At $\displaystyle \mathrm{T}(\mathrm{K})$, $\displaystyle 2$ moles of liquid A and $\displaystyle 3$ moles of liquid B are mixed. The vapour pressure of ideal solution formed is $\displaystyle 320$ mm Hg . At this stage, one mole of A and one mole of B are added to the solution. The vapour pressure is now measured as $\displaystyle 328.6$ mm Hg . The vapour pressure (in mm Hg ) of A and B are respectively:
