C. 
解释：
老师讲的公式是(Forward-spot)/spot=f，即Forward/spot-1=f,那不是应该1.5800/spot=1+0.05吗？讲解里写的是1-0.05，为什么呢？
NO.PZ2018062003000206 问题如下 Assume ththe exchange rate between CanUShcreaseto 1.5800. If the UShpreciate5% against the pricurrency, whiof the initiexchange rate is the most accurate between CanUS A.1.5048. B.1.6632. C.0.6646. B is correct.1.5800/initirate = 1-0.05initirate=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. 请问下列步骤错在哪里？已知spot rate 1.58 CAUS得spot rate 1/1.58 USC即 0.6239 USCA题UShpreciate5%所以previously 0.6239/0.95 = 0.6662 USC即 1.5011 CAUSD
