NO.PZ2017092702000018 问题如下 Given the scount rate of 4% a yecompounannually, the present value (PV)of 50,000, of the enof Ye5 (PV5 ), of the cash flow receivethe enof Ye20 is closest to: A.$22,819. B.$27,763. C.$28,873. B is correct. The PV in Ye5 of a $50,000 lump sum paiin Ye20 is $27,763.23 (where FV is future value): PV = FVN(1 + r)–N PV = $50,000(1 + 0.04)–15 PV = $27,763.23已知年化折现率为4%，按年计息，求在第20年末发生的一笔金额为50000的现金流在第五年末的现值为多少。计算器步骤如下N=15; I/Y=4; PMT=0; FV=-50,000; CPT PV =27763.22514 不应该是Y5的现值吗？也就是20年的折现到5年，5年再折现到现在啊？
