Two liquids X and Y form an ideal solution. At 300 K, vapour pressure of the solution containing 1 molof X and 3 mol of Y is 550 mm Hg. At the same temperature, if 1 mol of Y is further added to thissolution, vapour pressure of the solution increases by 10 mm Hg. Vapour pressure (in mmHg) of X andY in their pure states will be, respectively:
