That is a very simple mathematics question.tvb now,tvbnow,bttvb& P! R6 S2 i. L4 V) B
Let x = Male, y = Female, z = Child公仔箱論壇( c/ M) Y4 e. z. J8 t2 u- b0 K' Q3 J$ a
6x + 3y + z/2 = 100 Formula 1( q3 M+ z z0 z/ L+ ^ c! l/ H
x + y + z = 100 Formula 25.39.217.76# ?& N! {$ j2 n: E- ~
Simplify Formula 2 into z, we get z = 100 - x - y Formula 3 $ {8 `9 c# j) O7 h& J9 h( z( I" u+ FTVBNOW 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。Sub Formula 3 into Formula 1, we get 6x + 3y + ( 100 - x - y )/2 = 100 Formula 4tvb now,tvbnow,bttvb- Y: @, d, t. a: y T
Formula 4 can change into 11x + 5y = 100 Formula 5 , D6 I9 v: U2 Ntvb now,tvbnow,bttvbIn Formula 5, x can only be 0 - 9, otherwise y will be negative number which we dont want.# `+ P6 e+ K5 u
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. 7 s S9 I6 [( o9 i# m# B, _tvb now,tvbnow,bttvbEventually, 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
