That is a very simple mathematics question.5.39.217.76! a+ p- b! @2 [( C% S
Let x = Male, y = Female, z = Child 6 T' {6 k9 t) d. P6x + 3y + z/2 = 100 Formula 1tvb now,tvbnow,bttvb8 h, Y1 N5 Z; U+ i1 Z4 X
x + y + z = 100 Formula 25.39.217.76. k2 j0 s, x8 h3 ~' m& C
Simplify Formula 2 into z, we get z = 100 - x - y Formula 35.39.217.764 w9 ]5 |6 a( \; i' M
Sub Formula 3 into Formula 1, we get 6x + 3y + ( 100 - x - y )/2 = 100 Formula 4公仔箱論壇- b. ~& G+ f: t8 R9 S1 t) F
Formula 4 can change into 11x + 5y = 100 Formula 53 o5 j% @' F2 |6 [# M6 @ k
In Formula 5, x can only be 0 - 9, otherwise y will be negative number which we dont want. ; I2 K2 L5 S% @; D3 {5.39.217.76And 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. $ F+ L" _* z' s0 i, n7 E0 F公仔箱論壇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
