300 \text{ K}

, the vapour pressure of an ideal solution containing one mole of

A

and 3 mole of

B

, is 550 mm of Hg. At the same temperature, if one mole of

B

is added to this solution, the vapour pressure of solution increases by 10 mm of Hg. Calculate the V.P. of

A

and

B

in their pure state.
