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