[求助]GWD1-26 我已搜索，没人问过

If the units digit of the three-digit positive integer k is nonzero, what is the tens digit of k?

(1)     The tens digit of k + 9 is 3.

(2)     The tens digit of k + 4 is 2.

A. Statement (1) ALONE is sufficient, but statement (2) alone is not sufficient.

B. Statement (2) ALONE is sufficient, but statement (1) alone is not sufficient.

C. BOTH statements TOGETHER are sufficient, but NEITHER statement ALONE is sufficient.

D. EACH statement ALONE is sufficient.

E. Statements (1) and (2) TOGETHER are NOT sufficient.

答案选A，我觉得是C，如果k的个位是0，那么+9就不用进位，要是个位〉1就要进位，单个A怎么能确定个位是什么呢

你说的这题可以搜索啊，方法：如果GWD第3套Q5，则搜索的关键词：3-5

都明白了，是自己看题不细心.....

我真的搜索了GWD1-26，没有搜索到这道题，全部都是一道Invest的题， 所以我才发问的 

明白就好

搜索时用“1-26”比用“GWD1-26”好，你试试看

好的，谢谢阿！！！
