That is a very simple mathematics question.tvb now,tvbnow,bttvb6 U4 v0 r7 I9 I) | F3 F
Let x = Male, y = Female, z = Child / U6 @* U' ^( b8 g% i, [6x + 3y + z/2 = 100 Formula 1 , c! f# s( p- Y! [x + y + z = 100 Formula 2 , J- L5 s9 V5 }tvb now,tvbnow,bttvbSimplify Formula 2 into z, we get z = 100 - x - y Formula 3公仔箱論壇+ n' \7 ^8 \5 g
Sub Formula 3 into Formula 1, we get 6x + 3y + ( 100 - x - y )/2 = 100 Formula 4 , `7 a1 v1 H3 d7 Z: w/ m% O4 ?TVBNOW 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。Formula 4 can change into 11x + 5y = 100 Formula 5 # N+ h( D4 s$ w) t5.39.217.76In Formula 5, x can only be 0 - 9, otherwise y will be negative number which we dont want. 2 p% D3 C: w. h$ V1 B6 }5 U% X& O' f1 P5.39.217.76And 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3 X6 x/ _. d- R* R' e, D
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
