100 g of liquid A (molar mass `140g"mol"^(-1)`) was dissolved in 1000 g of liquid B (molar mass 180 `g"mol"^(-1)`) . The vapour pressure of pure liquid B was found to be 500 torr. What will be the vapour pressure of pure liquid A and its vapour pressure in the solution respectively if the total vapour pressure of the solution is 475 torr?

28.7 torr and 32 torr

280.7 torr and 32 torr
