问题如下:
The exchange rate between the Canadian dollar (CAD) and US dollar (USD) is 1.3245(CAD/USD=1.3245). Assume that the Canadian dollar (CAD) has appreciated 15 percent against US dollar (USD) during the past month. How much has the US dollar depreciated against the Canadian dollar?
选项:
A.
15%
B.
More than 15%
C.
Less than 15%
解释:
C is correct.
考点:Percentage Change in A Currency
解析:A货币对B货币的升值幅度不等于B货币对A货币的贬值幅度。
在本题中,[1/(1 + 0.15)] – 1 = (1/1.15) – 1 = -0.1304, or -13.04%.
老师,这种题是不是可以简单总结为升得多降得少?碰到好几道题都是这样的结果。
