That is a very simple mathematics question.公仔箱論壇0 s. g f, R9 s1 F& m J! G
Let x = Male, y = Female, z = Child5.39.217.76+ A$ e; E! ^9 Y0 P
6x + 3y + z/2 = 100 Formula 1 / C! s3 n# E/ g8 U+ G5.39.217.76x + y + z = 100 Formula 2tvb now,tvbnow,bttvb5 D6 }$ D" N8 Z' T% ~
Simplify Formula 2 into z, we get z = 100 - x - y Formula 3公仔箱論壇% ?% t2 }. B6 t: U" O7 m+ x: [
Sub Formula 3 into Formula 1, we get 6x + 3y + ( 100 - x - y )/2 = 100 Formula 4公仔箱論壇0 Z. F6 L4 n$ b" q% C2 G
Formula 4 can change into 11x + 5y = 100 Formula 5公仔箱論壇8 j3 E( \, z' z" I" V
In Formula 5, x can only be 0 - 9, otherwise y will be negative number which we dont want.5.39.217.76" a# z5 T. x2 E# S
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. ( e0 I+ z$ c3 |) X4 MEventually, 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
