That is a very simple mathematics question.0 e) b, y9 x/ v9 t1 X( X- c6 x4 X
Let x = Male, y = Female, z = Child
6x + 3y + z/2 = 100 Formula 1www3.tvboxnow.com5 E% q" N3 i5 _  _: n$ Q4 x7 H
x + y + z = 100 Formula 28 m; ~9 T* N1 z7 X& ]! n+ K
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。/ c; K: v, v  v/ W, t0 O
Sub Formula 3 into Formula 1, we get 6x + 3y + ( 100 - x - y )/2 = 100 Formula 45 {6 `: W; s& s  z) d
Formula 4 can change into 11x + 5y = 100 Formula 5TVBNOW 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。: O4 E: }- R3 ~+ S; a& V" C
In Formula 5, x can only be 0 - 9, otherwise y will be negative number which we dont want.
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 = 80.3 O: S, ?1 ?& k4 j+ X
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
