问一道题：NO.PZ2018062003000206

  1. CFA I
  2. Economics Analysis

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.

为什么这样做是错的？

CAD/USD=A initial rate 当USD贬值后，变成了1.58

USD=1/A CAD

贬值： USD=1/A *(1-5%) CAD

变成了CAD/USD=1.58 也就是USD=1/1.58CAD

1/1.58CAD=1/A *(1-5%) CAD

A=1.5010

同学，你的做法我还是看不懂

当USD贬值后 , 变成了1.58 USD=1/A CAD，这里我就不懂了为什么会变成这样。这里应该没有道理。而且你写的标价方式也不是标准的标价方式。

我们已经给出了正确的解法，所以你不用纠结于自己的方法，记住正确的做法就好了。

这是我的做法：CAD/USD=A initial rate 当USD贬值后，变成了1.58 USD=1/A CAD 贬值： USD=1/A *(1-5%) CAD 变成了CAD/USD=1.58 也就是USD=1/1.58CAD 1/1.58CAD=1/A *(1-5%) CAD A=1.5010
