That is a very simple mathematics question.tvb now,tvbnow,bttvb; W! ^- z% e. u$ e& _0 w
Let x = Male, y = Female, z = Child
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。& K/ X: @0 _5 z' j
x + y + z = 100 Formula 2公仔箱論壇 v* w% C4 y) Q3 n4 G' H0 e
Simplify Formula 2 into z, we get z = 100 - x - y Formula 3
Sub Formula 3 into Formula 1, we get 6x + 3y + ( 100 - x - y )/2 = 100 Formula 4
Formula 4 can change into 11x + 5y = 100 Formula 53 C1 z* s; L8 v: V. U1 ^
In Formula 5, x can only be 0 - 9, otherwise y will be negative number which we dont want.www2.tvboxnow.com) B$ u- `, X! P! O2 j
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.
Eventually, the answer is 20 female and 80 children and no male.
