问题如下：

A client requires £100,000 one year from now. If the stated annual rate is 2.50% compounded weekly, the deposit needed today is closest to:

选项：

A.

£97,500.

B.

£97,532.

C.

£97,561.

解释：

B is correct

because £97,531 represents the present value (PV) of £100,000 received one year from today when today’s deposit earns a stated annual rate of 2.50% and interest compounds weekly, as shown in the following equation (where FV is future value):

PV = FVN(1 + rs /m)mN PV = £100,000(1 +0.025/52 )-52 PV = £97,531.58.

如题。。。。。。。。。。。。。。。

@欢欢

一年=52周=365天都是确定的。

同学你好，

计算EAR的问题里，天数统一按照365天来处理。

此外本题对应的是一年有52周，不涉及到天数。

题目没说一年52周吧？
