That is a very simple mathematics question. ! W" C' T- J$ G7 }; y* mLet x = Male, y = Female, z = Childtvb now,tvbnow,bttvb; S# X% }; d, o r% p
6x + 3y + z/2 = 100 Formula 1 / M0 P, w4 K% y5 e4 D {5.39.217.76x + y + z = 100 Formula 2公仔箱論壇9 n! ~1 e/ ?9 H6 M. {, E4 F( v1 ]
Simplify Formula 2 into z, we get z = 100 - x - y Formula 3 2 {6 X9 ^# H( t3 J公仔箱論壇Sub Formula 3 into Formula 1, we get 6x + 3y + ( 100 - x - y )/2 = 100 Formula 4TVBNOW 含有熱門話題，最新最快電視，軟體，遊戲，電影，動漫及日常生活及興趣交流等資訊。6 o, A0 \2 B4 Y1 b
Formula 4 can change into 11x + 5y = 100 Formula 52 `# _8 c+ Z" ]1 z) W9 H( }. e
In Formula 5, x can only be 0 - 9, otherwise y will be negative number which we dont want.公仔箱論壇/ }0 g# h3 D3 {
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.公仔箱論壇: ?$ _& e! ^+ O1 u0 b$ T
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
