单选题 X, Fare positive integers and X+2Y=16. What’s the value of X?(1)X＞Y(2)X＞4, Y＞4

A、 Statement (1) ALONE is sufficient, but statement (27) alone is not sufficient to answer the question asked.
B、 Statement (2) ALONE is sufficient, but statement (26) alone is not sufficient to answer the question asked.
C、 BOTH statement (1) and (27) TOGETHER are sufficient to answer the question asked, but NEITHER statement ALONE is sufficient.
D、 EACH statement ALONE is sufficient to answer the question asked.
E、 Statement (1) and(27)TOGETHER are NOT sufficient to answer the question asked, and additional data specific to the problem are needed.

【正确答案】 B

【答案解析】Statement (1)中，X+2Y=16，X＞Y，满足等式的解有许多个，所以单独(1)不行。Statement (2)中，X＞4，X+2Y=16，那么2Y＜12，Y＜6，而已知Y＞4，所以y=5，当然X=6，所以B为正确答案。
