That is a very simple mathematics question.tvb now,tvbnow,bttvb: R, F; J# d# e6 U' p7 X
Let x = Male, y = Female, z = Child& J3 K$ T0 k" h! v
6x + 3y + z/2 = 100 Formula 1 7 P2 |1 |; u3 ~x + y + z = 100 Formula 2 - |8 f! ~- q" {( G7 n: `公仔箱論壇Simplify Formula 2 into z, we get z = 100 - x - y Formula 3' A( Z: T5 [% N! M* {
Sub Formula 3 into Formula 1, we get 6x + 3y + ( 100 - x - y )/2 = 100 Formula 4 ( u" Y) _: Q: S) U8 Mos.tvboxnow.comFormula 4 can change into 11x + 5y = 100 Formula 5) c) D) g# z+ I5 y8 t( Q
In Formula 5, x can only be 0 - 9, otherwise y will be negative number which we dont want.tvb now,tvbnow,bttvb; {6 L5 R& l f: E8 e/ S# U6 h8 f2 c
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.os.tvboxnow.com1 W5 M6 g" E' g4 j
Eventually, the answer is 20 female and 80 children and no male.作者: alan1234 時間: 2007-10-14 12:19 AM 標題: two answers
