The vapour pressures of two volatile liquids \( \mathrm{A} \) and \( \mathrm{B} \) at \( 25^{\circ} \mathrm{C} \) are 50 Torr and 100 Torr, respectively. If the liquid mixture contains 0.3 mole fraction of \( \mathrm{A} \), then the mole fraction of liquid \( B \) in the vapour phase is \( \frac{x}{17} \). The value of \( \mathrm{x} \) is
