Two liquid A and B form an ideal solution. The solution has a vapour pressure of 700 torr at `90^(@)C` . It is distilled till 2/3 rd of the solution is collected as condensate. The composition of the condensate is `X'_(A)=0.75` and that of the residue is `X''_(A)=0.3`. If the vapour pressure of the residue at `90^(@)` is 600 torr, which of the following option is incorrect?
