四、解答题(本大题 2个小题, 25小题 10分, 26小题 12分,共 22分)

25. 对任意一个三位数 n , 如果 n 满足各个数位上的数字互不相同, 且都不为零, 那么称这个数为“相异数”, 将一个“相异数”任意两个数位上的数字对调后可以得到三个不同的新三位数,把这三个新三位数的和与 111的商记为 F (n ) . 例如 n=123,对调百位与十位上的数字得到 213, 对调百位与个位上的数字得到 321, 对调十位与个位上的数字得到 132, 这三个新三位数的和为 213+321+132=666, 666÷111=6,所以 F (123) =6. (1)计算:F (243) , F (617) ;

(2)若 s , t 都是“相异数”,其中 s =100x +32, t =150+y (1≦ 错误!未找到引用源。 x ≦ 9, 1≦ 错误! 未找到引用源。 y ≦ 错误! 未找到引用源。 9, x , y 都是正整数) , 规定:()

t F s F k =, 当 ()()18=+t F s F 时,求 k 的最大值。

In order? to help rural? stude?nts grow talle?r and stron?ger, China?’s?Nutri?tion (营养) Impro?vemen?t Progr?am start?ed in 2011.
