Simplify Formula 2 into z, we get z = 100 - x - y Formula 35.39.217.768 v6 j# V1 V3 e: q0 q+ n% W. F7 z& e

In Formula 5, x can only be 0 - 9, otherwise y will be negative number which we dont want.tvb now,tvbnow,bttvb- ^6 ~* Q2 l6 d! _3 H' o& H& N8 s
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. / ^ j* C# E$ l! w! r2 u+ S XEventually, 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
