Malik's recipe for 4 servings of a certain dish requires 3/2 cups of pasta. According to this recipe, what is the number of cups of pasta that Malik will use the next time he prepares this dish?
(1) The next time he prepares this dish, Malik will make half as many servings as he did the last time he prepared the dish.
(2) Malik used 6 cups of pasta the last time he prepared this dish.
题目说做4份需要1.5杯. 问下次做的时候需要的多少杯 条件一说下次做的时候会做2份,那很显然只需要0.75杯了. 条件二说这个人上次做的时候用了6杯.上次做和下次做很显然不一样吧,所以无关. 因此选A.但是答案是C.
On July 1 of last year, the total number of employees at Company E was decreased by 10 percent. Without any change in the salaries of the remaining employees, the average (arithmetic mean) employee salary was 10 percent more after the decrease in number of employees than before the decrease. The total of the combined salaries of all of the employees at Company E after July 1 last year was what percent of that before July 1 last year?
(A) 90% (B) 99% (C) 100% (D) 101% (E) 110% 这题做对不难,答案是B.我想问一个问题就是: Without any change in the salaries of the remaining employees, the average (arithmetic mean) employee salary was 10 percent more after the decrease in number of employees than before the decrease.这个句子是不是自相矛盾了?现是说剩下的员工工资没有增长,在说工资的平均植又有增长. 请牛人解释... |
