问题如下图：PV=0，FV=-25000，I/Y=6/4，N=10*4，CPT PV=460.67
请问这个题目的计算器解答方式是这样的么？算不出来啊，我算的PV是13781.55

NO.PZ2017092702000017问题如下Given a stateannuinterest rate of 6% compounquarterly, the level amount that, positequarterly, will grow to £25,000 the enof 10 years is closest to:A.£461.B.£474.C.£836. A is correct. To solve for annuity (payment, when the future value (FV), interest rate, annumber of perio is known, use the following equation:lFV=A[(1+rsm)mN−1rm]25,000=A[(1+0.064)4×10−10.064]{l}FV=A{\lbrack\frac{{(1+\frac{r_s}m)}^{mN}-1}{\frrm}\rbrack}\\25,000=A{\lbrack\frac{{(1+\frac{0.06}4)}^{4\times10}-1}{\frac{0.06}4}\rbrack}lFV=A[mr(1+mrs)mN−1]25,000=A[40.06(1+40.06)4×10−1]A=460.68计算器按法6%/4=1.5%。所以I/Y=1.5，N=10*4=40，FV=25000，PV=0，CPT PMT=-460.6775. 为什么I/Y用的不是EAR/4?

NO.PZ2017092702000017 从那句话可以推断出这道题目的PV是0呢？
