The answer is 56%!

The is the way to solve it:

Male with brown eyes=4x
Female with brown eyes=7y
Male with blue eyes=x
Female with blue eyes=y

You get the total for blue is 22 and you can further make the system of equations:

4x+7y=133
x+y=22
After you solve this, you get x is 7 and y is 15.

Finally, plug it in to get to get 7 for the male blue eyes and 105 for the females brown eyes. Add them and you get 112. Make it into a fraction out of 200 which is 112/200 which further simplifies to 56%!
