That is a very simple mathematics question.
Let x = Male, y = Female, z = Childos.tvboxnow.com' U, a* T8 W8 i' b- ^0 r
6x + 3y + z/2 = 100 Formula 1tvb now,tvbnow,bttvb7 \* O( J$ c8 d6 l* L  y
x + y + z = 100 Formula 2
Simplify Formula 2 into z, we get z = 100 - x - y Formula 3公仔箱論壇  G) d$ j+ y; }) t
Sub Formula 3 into Formula 1, we get 6x + 3y + ( 100 - x - y )/2 = 100 Formula 42 [& F, m- I5 [. g/ l- M4 M( Q& f
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。3 o) R/ ^% U, u$ n  g3 i
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.tvb now,tvbnow,bttvb& A6 `3 E7 Z6 M2 o9 ~1 T- }# ~
Eventually, the answer is 20 female and 80 children and no male.
