问题如下：
Assume the CADJPY exchange rate has changed from CADJPY 82.4012 to 83.9912. The percentage change in the JPY price of a CAD is closest to:
选项：
A.−1.89%.
B.+1.89%.
C.−1.93%.
D.+1.93%.
解释：
The percentage change in the JPY price of a CAD is:
(83.9912 / 82.4012) − 1 = +0.0193 = +1.93%
由于加元的日元价格上涨，加元相对于日元升值，现在1加元可以购买多1.93%的日元。加元相对于日元升值了1.93%。
因为问的是JPY/CADpercentage的变化， 那为什么不是1/82.40125-1/83.9912=0.0121-0.0119？
