You are a male and you have three brothers and three sisters. Each of your sisters has two sisters and 4 brothers. There are four boys and three girls in the family. (Warning : algebraic solution!) For you as a male sibling, B (boys) = S (girls).
For any of your sisters , B+1 = (S-1)/2.
Solving the equations simultaneously, S-2=1, and S=3, B=3.
