Two liquids ' A ' and ' B ' form an ideal solution. At 300 K , the vapour pressure of a solution containing 1 mole of ' A ' and 3 moles of ' B ' is 550 mm Hg . At the same temperature, if one more mole of ' B ' is added to the solution, the vapour pressure of solution increases to 560 mm Hg . Then the ratio of vapour pressures of A and B in their pure state is
