题目
When 26 is divided by K, the remainder is K-2. K >= 2
Quantity A
Sum of all possible values of K
选项
C.The two quantities are equal.
D.The relationship cannot be determined from the information given.
解析
任意数 N 除以除数 x 可表示为: N = xQ + 余数
这里, 26 = KQ + (K - 2)
即 26 + 2 = K(Q + 1)
K = 28/(Q+1)
当 Q = 0 时, K = 28
当 Q = 1 时, K = 14
当 Q = 3 时, K = 7
当 Q = 6 时, K = 4
当 Q = 13 时, K = 2
当 Q = 27 时, K = 1
A栏:所有可能的 K 值之和为56
B栏:55
因此,选A。
