If p and q are positive integers and pq = 24, what is the value of p ?
(1) ~$q \over 6$~is an integer.
(2) ~$p \over 2$~is an integer.
Statement (1) ALONE is sufficient, but statement (2) alone is not sufficient.
Statement (2) ALONE is sufficient, but statement (1) alone is not sufficient.
BOTH statements TOGETHER are sufficient, but NEITHER statement ALONE is sufficient.
EACH statement ALONE is sufficient.
Statements (1) and (2) TOGETHER are NOT sufficient.
题目分析:
(1) q=6,p=4满足条件1;q=12,p=2,也满足条件1,因此条件1不能确定p的值。
(2) p=2,q=12满足条件2;p=4,q=6也满足条件2,因此条件2不能确定p的值。
条件1的分析中的两个例子既满足条件1又满足条件2,同样无法确定p的值。
因此,本题答案为(E),两个条件结合起来也不能解题,必须提供新数据。
4*6 or 2*12
