That is a very simple mathematics question.tvb now,tvbnow,bttvb2 D# B/ Y4 [) k. ~. y0 f
Let x = Male, y = Female, z = Child公仔箱論壇3 @1 M2 z+ i" g* v7 H4 W( I

Simplify Formula 2 into z, we get z = 100 - x - y Formula 3
- N/ @. p. K5 b' s5 qSub Formula 3 into Formula 1, we get 6x + 3y + ( 100 - x - y )/2 = 100 Formula 4
& _/ c* R9 k0 @( j  _, IFormula 4 can change into 11x + 5y = 100 Formula 5
' T) {  @$ c8 Q1 @5.39.217.77:8898In Formula 5, x can only be 0 - 9, otherwise y will be negative number which we dont want.
4 j) H' T9 Z3 \$ ztvb now,tvbnow,bttvbAnd between 0 and 9, only 0 can give me a single number of y. So, x has to be 0 and y have to be 20. Then put x and y back to formula 1, we get z = 80.& u' y. @* B  l7 n8 O* K
Eventually, the answer is 20 female and 80 children and no male.
