That is a very simple mathematics question.% D' n7 ?; ~& @
Let x = Male, y = Female, z = Child公仔箱論壇  d2 ]) D* g+ h* j. L9 s
6x + 3y + z/2 = 100   Formula 1
0 X5 j2 s, G* k* ?$ D4 w* Hx + y + z = 100    Formula 2
/ t/ D- [9 {6 d9 s! q" ]Simplify Formula 2 into z, we get z = 100 - x - y Formula 3$ \; V+ E! U) Z+ f( M+ M
Sub Formula 3 into Formula 1, we get 6x + 3y + ( 100 - x - y )/2 = 100 Formula 4

In Formula 5, x can only be 0 - 9, otherwise y will be negative number which we dont want.
1 P# k* V6 K) w9 J& j( N' m% t7 ytvboxnow.comAnd 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.
