228、DS 说是26被一个数K除,余数是K-2,问K的取值 (1)说这个数是个质数 (2)10<k<30 119题变体 参考答案: 条件1, k=7或者2 条件2, k可以取14或者28 k取值不唯一,所以应该选择E。 附OG说明:In data sufficiency problems that ask for the value of a quantity, the data given in the statements are sufficient only when it is possible to determine exactly one numerical value for the quantity.
