我说一下我的思路哈

  1. CFA I
  2. Economics Analysis

NO.PZ2018062003000206

问题如下：

Assume that the exchange rate between CAD and USD has decreased to 1.5800. If the USD has depreciated by 5% against the price currency, which of the initial exchange rate is the most accurate between CAD and USD?

选项：

A.

1.5048.

B.

1.6632.

C.

0.6646.

解释：

B is correct.

1.5800/initial rate = 1-0.05

initial rate=1.58/0.95 = 1.6632.

考点： Percentage Change in A Currency

解析:

1.5800/初始汇率= 1-0.05

初始汇率=1.58/0.95 = 1.6632.

我看了所有的提问，也看了您的答案，但我没太看明白您的解释，我是这样想的哈，假设1.58CAD能换1美元是因为USD对CAD（price currency）跌了5%，反退回来也就意味着 x CAD = 1USD/0.95 也就是1.58/0.95也就是汇率了是吧
