[转帖]819少量数学

作文:1.The following appeared as part of a recommendation from the business manager of a department store.

“Local clothing stores reported that their profits decreased, on average, for the three-month period between August 1 and October 31. Stores that sell products for the home reported that, on average, their profits increased during this same period. Clearly, consumers are choosing to buy products for their homes instead of clothing. To take advantage of this trend, we should reduce the size of our clothing departments and enlarge our home furnishings and household products departments.”

2. “All groups and organizations should function as teams in which everyone makes decisions and shares responsibilities and duties. Giving one person central authority and responsibility for a project or task is not an effective way to get work done.”

数学 8.19

1.  一个数x除以53,除以74,数y除以53,除以74 x ,y之差一定能被多少整除。

思路:x,y的通式都一样,为35M+NN不求无所谓,因为x,y情况完全一样。如果想求N, 方法为:最小满足除以53,除以74的数是18,所以通式为35M+18),所以xy之差必然为35的倍数,选35

2. 数轴上从左到右依次有点AB,C,D, E,F,G    七个点(有图示), 点的间距都相等,已知G点坐标是312 F点坐标是311 问以下哪个点的坐标是 312D点坐标满足,选D

3.  已知a-b, a/b 都是偶数,a,b 都是整数。问下面哪一个一定是奇数。

A.    a/2, B. b/2,  C. (a+b)/2, D. (a+2)/2, E. (b+2)/2

这题选D

代入数字法:(1a=12,b=2 , 排除AE

            (2) a=8, b=4, 排除BC

此外,还有一些JJ上的题,例如货物价值〉499那题,golf抛物线那题,P^xy,  JJ 上的答案几乎都是正确的,前人的劳动就是值得尊重啊。


VERBAL考得太差,不得不准备2战。阅读有:CEO, 皮肤呼吸。

祝大家好运了。
