That is a very simple mathematics question. ' S+ u" u6 F0 {4 x% c; t! e8 I. b公仔箱論壇Let x = Male, y = Female, z = Child 9 k+ ]0 O4 z4 }8 z. otvb now,tvbnow,bttvb6x + 3y + z/2 = 100 Formula 1 " g) Y+ j* @4 y: mtvb now,tvbnow,bttvbx + y + z = 100 Formula 2( X+ J- s- G8 b8 P0 B3 {

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 = 80.5.39.217.76% S1 L7 y# Q: j
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
