That is a very simple mathematics question.
2 G- b/ @% b- ?1 I, u9 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。Let x = Male, y = Female, z = Child
! {* h% M5 o* j6 f6 M: ios.tvboxnow.com6x + 3y + z/2 = 100   Formula 1& e) f: x4 t* \* G" _5 [; c
x + y + z = 100    Formula 2公仔箱論壇! F7 Q5 }, |" ~! L" E
Simplify Formula 2 into z, we get z = 100 - x - y Formula 3公仔箱論壇) n) _* I' U: A6 e8 ]
Sub Formula 3 into Formula 1, we get 6x + 3y + ( 100 - x - y )/2 = 100 Formula 4
, h, o% s/ M! qos.tvboxnow.comFormula 4 can change into 11x + 5y = 100 Formula 5$ U4 F: E" a. b" t
In Formula 5, x can only be 0 - 9, otherwise y will be negative number which we dont want.
2 I( G; @2 j1 r2 `5 J( {" }- @5 btvb now,tvbnow,bttvbAnd 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.os.tvboxnow.com8 p( Y# j; v9 |8 s! l! T
Eventually, the answer is 20 female and 80 children and no male.
