That is a very simple mathematics question.
  n5 _& Z- y0 P# Jtvb now,tvbnow,bttvbLet x = Male, y = Female, z = Child

x + y + z = 100    Formula 2tvb now,tvbnow,bttvb5 O+ ^* O8 {2 ^
Simplify Formula 2 into z, we get z = 100 - x - y Formula 3# F  K6 o  A% N6 J; G( r: o
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.公仔箱論壇# w  |8 @* v( _! Y4 B/ B8 a; {
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 = 80.4 T) X& i+ q+ F. b( W$ c
Eventually, the answer is 20 female and 80 children and no male.

two answers

man,female,children
