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.
现在CAD/USD=1.58,所以CAD=1.58USD.
USD贬值了,所以 0.95×原来的USD=USD
带入就要CAD=1.58USD=1.58* 0.95×原来的USD=1.501原来的USD
得到:CAD/原来的USD=1.501,选A。。。。
