请教一道OG 12 Diagnostic Data Sufficiency的题:
T40. If $5,000 invested for one year at p percent simple annual interest yields $500, what amount must be invested at k percent simple annual interest for one year to yield the same number of dollars?
(1) k=0.8p
(2) k=8
答案是D。我很费解。。。。这里是怎么反映出k和p的关系的呢??
小女不才,刚开始复习,才做到诊断测试的DS部分就屡现困惑……=_,=
还请大家多指点!谢谢!

由题意求出p=0.1
知道k和p的关系就可以得出k的值,所以1可以
2直接给出k的值,所以也对
啊,明白了,是由给定的1或2求要存的钱来着,弄混条件了,多谢ls MM =)
