Two liquids A and B form ideal solutions. At 300 K, the vapour pressure of solution containing 1 mole of A and 3 mole of B is 550 mm Hg. At the same temperature, if one more mole of B is added to this solution, the vapour pressure of the solution increase by 10 mm Hg. The vapour pressure of A and B in their pure state (in mm Hg) respectively are
