NO.PZ2017092702000005 问题如下 A client requires £100,000 one yefrom now. If the stateannurate is 2.50% compounweekly, the posit neetoy is closest to: A.£97,500. B.£97,532. C.£97,561. B is correbecause £97,531 represents the present value (PV) of £100,000 receiveone yefrom toy when toy’s posit earns a stateannurate of 2.50% aninterest compoun weekly, 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. 我用的计算器第三排按出来的,是对的吗?答案解析里怎么用的EAR公式?

NO.PZ2017092702000005 £97,532. £97,561.
