An ideal solution contains two volatile liquids \( A\left(P^{\circ}=100\right. \) torr \( ) \) and \( B\left(P^{\circ}=200\right. \) torr \( ) \). If mixture contain 1 mole of \( A \) and 4 mole of \( B \) then total vapour pressure of the distillate is:
(a) 150
(b) 180
(c) \( 188.88 \)
(d) \( 198.88 \)
