以下思路哪里错了呢

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.

Usd作为价格货币,在分母上.应该直接贬值后的规律1.5890乘以0.95

嗨,努力学习的PZer你好:


同学你好,并不是呢,正确的公式应当是原版的价格方式*base的贬值情况=最终的价格。
