NO.PZ2017092702000028 问题如下 investor performs the following transactions on the shares of a firm.• t = 0, she purchases a share for $1,000. • t = 1, she receives a vinof $25 anthen purchases three aitionshares for $1,055 each. • t = 2, she receives a totvinof $100 anthen sells the four shares for $1,100 each. The money-weighterate of return is closest to: A.4.5%. B.6.9%. C.7.3%. B is correct.Computation of the money-weightereturn, r, requires finng the scount rate thsets the present value (outflows) equto the present value (inflows). Solving for r, 1,000+3,1651+r=251+r+4,500(1+r)21,000+\frac{3,165}{1+r}=\frac{25}{1+r}+\frac{4,500}{{(1+r)}^2}1,000+1+r3,165​=1+r25​+(1+r)24,500​ results in a value of r = 6.91% 是输完现金流，按IRR再按CPT就行吗，为什么显示error 5
