At $T(K), 2$ moles of liquid $A$ and 3 moles of liquid $B$ are mixed. The vapour pressure of ideal solution formed is 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 328.6 mm Hg . The vapour pressure (in mm Hg ) of A and B are respectively:
