That is a very simple mathematics question.tvb now,tvbnow,bttvb( v. ~% v1 ]" y- Q0 q% O
Let x = Male, y = Female, z = Child
$ l2 x- t+ e2 I1 n! [. M  c公仔箱論壇6x + 3y + z/2 = 100   Formula 1TVBNOW 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。! M4 ~+ p, r2 Q( |* v1 D6 }- N- V
x + y + z = 100    Formula 2
* m, e3 m5 z" U: ?& h# Q; ^5.39.217.76Simplify Formula 2 into z, we get z = 100 - x - y Formula 3
2 c; U/ B5 Y& ^& G4 f! ~2 L. ^5.39.217.76Sub Formula 3 into Formula 1, we get 6x + 3y + ( 100 - x - y )/2 = 100 Formula 4
7 w) w, A* G- L5 T% _公仔箱論壇Formula 4 can change into 11x + 5y = 100 Formula 5
  S/ {. ?" D6 L/ p% q* IIn Formula 5, x can only be 0 - 9, otherwise y will be negative number which we dont want.
9 [- Y. D6 r0 O- Q, v公仔箱論壇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 = 80.5.39.217.76' F  T8 k9 k' d: J
Eventually, the answer is 20 female and 80 children and no male.
