joan actually likes 30% of her male friends and 20% of her female friends.
she has a total of 200 friends, 45% of them are male.
how many female friends does joan actually like?
:
45% of her 200 friends are boys
.45 * 200 = 90 boys
Then
200 - 90 = 110 girls
:
She likes:
.20 * 110 = 22 girls, she likes

Kind of silly, someone you dislike is not a friend, is it?
