At 300 K, the vapour pressure of an ideal solution containing 1 mole of A and 3 moles of B is 500 mm Hg. At the same temperature, 2 moles of B are added to this solution. The vapour pressure of solution increases by 10% of the original vapour pressure. Correct statements about the vapour pressure areA. Vapour pressure of A in the pure state is 50 mm HgB. Vapour pressure of B in the pure state is 650 mm HgC. Ratio of final pressure to the initial vapour pressure is 1:0.5D. Ratio of vapour pressure of pure B to the vapour pressure of pure A is `13:1`
