A solution is made by mixing one mole of volatile liquid A with $\displaystyle 3$ moles of volatile liquid B. The vapour pressure of pure A is $\displaystyle 200$ mm Hg and that of the solution is $\displaystyle 500$ mm Hg . The vapour pressure of pure B and the least volatile component of the solution, respectively, are:
