That is a very simple mathematics question.
1 [0 p! x5 a  c& d( V- o* ALet x = Male, y = Female, z = ChildTVBNOW 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。. t3 d! F3 K! Z% }7 S; R
6x + 3y + z/2 = 100   Formula 1公仔箱論壇1 Y, ?, f  ^- J3 y, ]0 W1 K
x + y + z = 100    Formula 2
8 U- w* X/ Q  i  S4 stvb now,tvbnow,bttvbSimplify Formula 2 into z, we get z = 100 - x - y Formula 33 b% \' F$ H5 D& T3 m% V6 }3 X; l
Sub Formula 3 into Formula 1, we get 6x + 3y + ( 100 - x - y )/2 = 100 Formula 4! F% K7 C' U- @6 n$ A6 Z
Formula 4 can change into 11x + 5y = 100 Formula 5tvb now,tvbnow,bttvb5 D! b- `; ?( R4 |
In Formula 5, x can only be 0 - 9, otherwise y will be negative number which we dont want.
! }0 O$ }, \2 W4 U. \tvb now,tvbnow,bttvbAnd 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.公仔箱論壇+ W; ~  h! R& o5 S+ h4 _6 K
Eventually, the answer is 20 female and 80 children and no male.
