Question
An expert examines the following spot exchange rate data:
USD/CAD 1.3852
USD/ZAR 18.2124
What is the closest ZAR/CAD cross rate?
选项:
A.0.0741. B.0.076 C.12.34解释:
Solution
The formula for ZAR/CAD cross rate becomes:
USD/CAD × (USD/ZAR)^-1 = USD/CAD × ZAR/USD = 1.3852 / 18.2124 ≈ 0.076
•
ZAR/CAD交叉汇率公式为:
USD/CAD × (USD/ZAR)^-1 = USD/CAD × ZAR/USD = 1.3852 / 18.2124 ≈ 0.076
这道题为什么不是18.2124/1.3852?
首先两个usd在分子上,所以用除法
然后题目问的是ZAR/CAD的cross rate,难道不是用18.2124USD/ZAR 除以1.3852 USD/CAD吗
