That is a very simple mathematics question.: F4 v$ J; c7 G+ e6 h2 @: ]
Let x = Male, y = Female, z = Child! A: k) V- u4 P# K# J0 d
6x + 3y + z/2 = 100 Formula 1 ' L$ U, ?$ l. j2 J* s4 I6 yx + y + z = 100 Formula 2 y. ~! x4 h4 W9 f公仔箱論壇Simplify Formula 2 into z, we get z = 100 - x - y Formula 36 B2 i6 T# m" R9 r" `5 W3 e
Sub Formula 3 into Formula 1, we get 6x + 3y + ( 100 - x - y )/2 = 100 Formula 43 Q F# N1 ^" q% ^
Formula 4 can change into 11x + 5y = 100 Formula 5 4 P3 |) s- q& R; h- r9 uTVBNOW 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。In Formula 5, x can only be 0 - 9, otherwise y will be negative number which we dont want. * L! z* D& x: B. e4 Y3 [% }. i' JAnd 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.% m3 ?! v! k" X/ m# ^
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
