Two liquids A and B form an ideal solution, the vapour pressure of pure A and pure B at 373 K are 400 and 300 mmHg respectively. Vapours above the solution are composed of 3 moles of A and 2 moles of B are collected and condensed to other container. The transferred liquid in the other container is then heated at 100°C. If the mole fraction of A in the final drop present in liquid state is X, then the value of 100X to the nearest integer is
