Question

A company surveyed 1200 people. Twice as many females as males. How many each were surveyed

Answer 1

Females: X

Males: Y

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

The total surveyed are:

`x+y=1200`
`2y+y=1200`

Then we have:

`3y=1200`
`y=(1200)/(3)=400`

From the first equation:

`x=1200-y=1200-400=800`

So, males are 400 and females are 800.
