Hmmmm. Alighted? My Lord, were they flying?
Anyway, 1/3 of 60 percent is 20 percent, so on the bus remains 40 percent male and 40 percent female
PrecentMaleThere= 40/80=50 percent
X = The # of people on bus.
0.6X = The # of males on bus.
(1/3) * 0.6X = 0.2X = The # of males exited bus.
0.6X - 0.2X = 0.4X = The # of males
remaining on bus.
X - 0.2X = 0.8X = The # of people on bus.
%Male = 0.4X / 0.8X = 0.5 = 50% = Percentage of male remaining on bus.
100% - 50% = 50% Females.
