That is a very simple mathematics question.os.tvboxnow.com0 ~/ p! M4 f, e+ S' w9 r; D& u
Let x = Male, y = Female, z = Childos.tvboxnow.com2 J. b; W/ b; B4 B
6x + 3y + z/2 = 100 Formula 1
x + y + z = 100 Formula 2公仔箱論壇( f" N0 m; A% ]. {: O
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' l. q# R: t! x5 U: \5 I0 \; m' g
Formula 4 can change into 11x + 5y = 100 Formula 5os.tvboxnow.com8 t! t0 \$ r8 r; a5 m
In Formula 5, x can only be 0 - 9, otherwise y will be negative number which we dont want.
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.tvb now,tvbnow,bttvb3 f7 P L' P, o- X2 f3 c: t9 [
Eventually, the answer is 20 female and 80 children and no male.
