At `80^(@)C` the vapour pressure of pure liquid 'A' is 520 mm Hg and that of pure liquid 'B' is 1000 mm Hg. If a mixture solution of 'A' and 'B' boils at `80^(@)C` and 1 atm pressure, the amount of 'A' in the mixture is (1 atm `= 760 mm Hg)`

A

`(T_(1))/(t_(1))=7/17`

B

`(T_(10))/(T_(11))=17/7`

C

`(t_(6))/(T_(6))=45/19`

D

`(t_(6))/(T_(6))=19/45`
