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.

看不懂解释 我的做法是 根据f=F-S 得出-1.5800=95%S-S 最终S=0.05/0.000158=316.4556962

嗨，从没放弃的小努力你好：


同学你好，根据你的公式（f=forward/spot -1)，应该是1.58/s-1=-0.05.
