Each of my sons has as many brothers as sisters, but each of my daughters has only half as many sisters as brothers.
How many children do i have?

#Sons = s, #Daughters = d
s1 = d
d1 = s/2
>
s = 4
d = 3 
I certainly don't have an equation for this, but I believe there would be 7 children....4 boys and 3 girls. That would mean each boy has 3 brothers and 3 sisters and each girl has 4 brothers and 2 sisters.

#sons = h #daughters = d brothers = b sisters = s
h = b+s
d = h/2
so if you have one daughter you have two sons and so on so forth because the daughters only equal half of the sons.
