That is a very simple mathematics question.tvb now,tvbnow,bttvb ^. }1 v6 T4 g4 U
Let x = Male, y = Female, z = Child
6x + 3y + z/2 = 100 Formula 1
x + y + z = 100 Formula 2公仔箱論壇- G' o$ ^* l0 n5 ]
Simplify Formula 2 into z, we get z = 100 - x - y Formula 3TVBNOW 含有熱門話題，最新最快電視，軟體，遊戲，電影，動漫及日常生活及興趣交流等資訊。! w# B1 v+ ]# O4 U& N
Sub Formula 3 into Formula 1, we get 6x + 3y + ( 100 - x - y )/2 = 100 Formula 4公仔箱論壇. O) n! @% r+ Z: k$ I8 V
Formula 4 can change into 11x + 5y = 100 Formula 5
In Formula 5, x can only be 0 - 9, otherwise y will be negative number which we dont want.- n! T. L, ~8 s0 ?! p% h0 \$ S! v$ O
And 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.tvb now,tvbnow,bttvb3 F6 g4 k$ `" f, z
Eventually, the answer is 20 female and 80 children and no male.

11x + 5y = 100 Formula 5

11X must be 0 or multiple of 5
that meanz x must be 0 or 5
