Two liquids X and Y form an ideal solution. At 300K, 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 mmHg) of X and Y in their pure states will be, respectively :-
