That is a very simple mathematics question.; D1 { H" e9 C5 S

x + y + z = 100 Formula 2 - L!

In Formula 5, x can only be 0 - 9, otherwise y will be negative number which we dont want.公仔箱論壇7 t5 J+ H4 Q" W8 _$ M- _
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.公仔箱論壇" b' S' b6 r0 x3 B6 V# s8 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
