问题如下：

An exchange rate between two currencies has increased to 1.4500. If the base currency has appreciated by 8% against the price currency, the initial exchange rate between the two currencies was closest to:

选项：

1.3340.

1.3426.

1.5660.

解释：

B is correct.

The percentage appreciation of the base currency can be calculated by dividing the appreciated exchange rate by the initial exchange rate. In this case, the unknown is the initial exchange rate. The initial exchange is the value of X that satisfies the formula:

1.4500/X = 1.08

Solving for X leads to 1.45/1.08 = 1.3426.

考点： Percentage Change in A Currency

解析:

1.4500/初始汇率= 1.08.

初始汇率= 1.45/1.08 = 1.3426

对于A、B两种货币，以下两种表达：

1.45A/B

A/B=1.45

分别哪个是base currency, 哪个是price currency?

嗨，努力学习的PZer你好：

分别哪个是base currency, 哪个是price currency?

Hello，亲爱的同学！

/后的是base currency，/前的是price currency。

所以对于A/B 汇率，B是base currency，A是price currency。

同学记忆住这个知识点就好了。
