GMAT OG上 DS题一道~
If $5000 invested for one year at p percent simple annual interest yield $500,what amount must be invested at k percent simple annual interest for one year to yield the same number of dollar
1)k=0.8p 2)k=8
答
怎么还有在这里问DS题的呵呵，去CD上讨论的比较多啦~~
选D啦，只要知道K的就能求。根据题目可以求P ，所以条件1和2都能求~
答
答案是d吧,两个条件分别满足
5000*p/100=500
p=1
而问题,
也就是x*k/100=500
求x只要知道k就行了,所以,两个条件都满足,选d
