问题如下图:
选项:
A.
B.
C.
解释:
已经迷失在TODAY,12年,13年FIRST PAYMENT, 和32年的图里,是不是可以这样理解题目,今天计划买一笔后付年金,这个年金前12年每年要投入一笔钱进去,才可以在第13年的时候开始收钱,每年收2000计发20年,那么在第32年年末所有的年金都发完了,收益率按7%计算, 前期投入在12年里需要累计投入21,188.03才可以拿到后续的钱,假如在今天这个时间点选择一次性投入相当于需要拿出9407.74的钱。
NO.PZ2015120604000013问题如下 annuity of $2,000 per yewill receivefor twenty years. The first payment is to receivethe enof thirteenth years. Assume the scount rate is 7% over next years, calculate the toy's present value of the annuityA.$8,792.B.$9,408.C.$10,066. B is correct. Calculate the PV of annuity the enof the twentieth years : N = 20; I/Y = 7; PMT = -2,000; FV = 0; CPT PV = 21,188.03. ; Calculate the PV toy: N = 12; PMT = 0; FV = -21,188.03; I/Y = 7; CPT PV = 9,407.74. 这题时间线没看懂能不能一下
