That is a very simple mathematics question.
" A% d" w" [1 L$ Z; y5 A1 p" ULet x = Male, y = Female, z = Child
& v7 g6 C1 [+ f3 Z. b0 A: a6x + 3y + z/2 = 100   Formula 1) n! J7 \) W- v( [
x + y + z = 100    Formula 28 H2 o+ ^) K0 d- S# F6 _: v
Simplify Formula 2 into z, we get z = 100 - x - y Formula 32 n! v/ m7 }9 v+ m! w; ^3 i5 r
Sub Formula 3 into Formula 1, we get 6x + 3y + ( 100 - x - y )/2 = 100 Formula 4

In Formula 5, x can only be 0 - 9, otherwise y will be negative number which we dont want.

Eventually, the answer is 20 female and 80 children and no male.
