That is a very simple mathematics question.TVBNOW 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。8 X: k: U# X3 [. N
Let x = Male, y = Female, z = Childwww1.tvboxnow.com4 r/ M6 f; l" y" k( \) N; R: o0 R
6x + 3y + z/2 = 100   Formula 10 [3 v" Z% O& w& G; c
x + y + z = 100    Formula 2公仔箱論壇& b- O: g' N. `$ X: ^( v
Simplify Formula 2 into z, we get z = 100 - x - y Formula 3
  G2 |( q$ r! F& hSub Formula 3 into Formula 1, we get 6x + 3y + ( 100 - x - y )/2 = 100 Formula 4
1 M# u, q5 ]4 ?9 T, {公仔箱論壇Formula 4 can change into 11x + 5y = 100 Formula 5tvb now,tvbnow,bttvb3 I# ~( s; W$ g9 Z8 ]+ o
In Formula 5, x can only be 0 - 9, otherwise y will be negative number which we dont want.
( {# E+ M. x3 [4 S$ _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.
+ ]1 U: W6 ?* R3 @3 nEventually, the answer is 20 female and 80 children and no male.

that meanz x must be 0 or 5
