一条路上有三个交通灯，每个交通灯分红绿黄三种颜色，红灯持续时间为30秒，绿灯为35秒，黄灯为8秒，按照以上的时间和顺序轮换，问正午（noon)以后三个灯至少有一秒钟同时为绿灯吗？

 

 

               
  （1）三个灯35分钟前都不是绿灯

               
  （2）一个灯变红灯比第二个灯早15秒，比第三个灯早30秒

 

 

[解] 选B。这题我粗算了一下﹐不一定准。条件1不能满足。不知到这3个灯绿的时间有没有重迭的部份。条件2应该可以。我划了一下好像有5秒的重迭。你可以划划再验证一下。

 

小学奥数作过这样的题，现在不懂啊，能否不要讲的太抽象！！

谢了

(1)由于周期为73s,35分钟不是周期的倍数,所以什么情况都能发生

(2)画时间轴就好了

我的网速恐怕做不了这样的壮举。。。。

据我统计最近的哀嚎(关于prep的)，基本能加强我的观点，1.1比1.0难度上升了一些。而且更接近真实考试情况。

所以，强烈建议大家多感悟prep的SC部分。。。

另外：3M兄弟

你的逻辑JJ这题答案给错了吧？

Q40:

A manufacturer of workstations for computer-aided design seeks to increase sales to its most important corporate customers.  Its strategy is to publish very low list prices for workstations in order to generate interest among the buyers for those corporations.

低价àsale上升

Which of the following, if characteristic of the marketplace, would tend to cause the manufacturer’s strategy to fail?

 

1. The proposed list prices would seem low to a typical buyer for the manufacturer’s most important corporate customers.
2. The capabilities of workstations suitable for given jobs are not significantly different among various manufacturers.
3. The manufacturer’s most important corporate customers employ as buyers persons who are very knowledgeable about prices for workstations for customer-aided design.
4. Customers differ significantly in the percentage of resources they can devote to computer workstations.
5. Buyers for corporations that purchase workstations for computer-aided design receive bonuses for negotiating large discounts from the list price.

   Answer: D

=========

应该是E吧。。。。

看了你的逻辑JJ又恢复点信心，这些题原来在gwd里出现的时候基本上都是一次做对。。。

晕,是E阿,可能是写错了
