NO.PZ2016010802000207 问题如下 A aler provis the following quotes:The spot ZAR/HKcross-rate is closest to: A.0.9205. B.1.0864. C.1.2978. is correct.To get to the ZAR/HKcross-rate, it is necessary to take the inverse of the CNY/Zspot rate anthen multiply the CNY/HKexchange rate:(ZAR/HK =(CNY/ZAR)−1×(CNY/HK(ZAR/HK;=(CNY/ZAR)^{-1}\times(CNY/HK(ZAR/HK(CNY/ZAR)−1×(CNY/HK= (1/0.9149) × 0.8422 = 0.9205考点 cross-rate解析(ZAR/HK =(CNY/ZAR)−1×(CNY/HK(ZAR/HK;=(CNY/ZAR)^{-1}\times(CNY/HK(ZAR/HK(CNY/ZAR)−1×(CNY/HK= (1/0.9149) × 0.8422 = 0.9205 为啥呢

老师 我这样想 对吗?
