Females: X

Males: Y

X=2Y because "Twice as many females as males"

The total surveyed are:

[tex]x+y=1200[/tex][tex]2y+y=1200[/tex]

Then we have:

[tex]3y=1200[/tex][tex]y=\frac{1200}{3}=400[/tex]

From the first equation:

[tex]x=1200-y=1200-400=800[/tex]

So, males are 400 and females are 800.
