The following data sufficiency problems consist of a question and two statements, labeled (1) and (2), in which certain data are given. You have to decide whether the data given in the statements are sufficient for answering the question. Using the data given in the statements plus your knowledge of mathematics and everyday facts (such as the number of days in July or the meaning of counterclockwise), you must indicate whether.
If all apples at a certain grocery store are equally priced, and all pears at the same grocery store are equally priced, what is the same price of a pear ？（）
(1) Eight pears cost eighty cents more than eight apples.
(2) Ten apples cost twenty cents more than eight pears.
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.
参考答案：C
解析：
alone is insufficient because it does not give the price of either item. (2) alone is insufficient because it does not give the price of either item. If the statements are combined, you can determine that the addition of two apples increased the value of the bundle of apples as opposed to the bundle of pears by $1.00, so each apple must be worth $0.50. From (1), we know that each pear costs $0.10 more than each apple, so each pear is worth $0.60.
