On Monday a store had a sale on bottles of juice S and juice T. If the total number of bottles of juice S in stock were sold on Monday, for which juice, S or T, were more of the bottles sold that day? (1) Two-thirds of the total number of bottles of juice T in stock were sold on Monday. (2) At the beginning of the sale, there was a total of 90 bottles of juice S and 60 bottles of juice T in stock. 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. 这道题我觉得应该选A,我的思路是设总共卖了x,那么s就应该是(1/2)x,A的条件是T卖出了2/3，那么就可以表示为(2/3)x．x都是指卖出的总数，这样就可以比较出谁多了．请问我的思路错在什么地方．请大家帮我看一下，谢谢各位了． |
