计算mwrr时，使用计算器，CF0= -10,000,000, CF1=10,000,000*14%-100,000,000= -98,600,000 , CF2=110,000,000*8%=8,800,000, IRR=-91.15。与答案r=8.53%非常不一样，错在哪里？

The funattracts another $100 million the start of Ye2 anearns a return of 8% for thyear. The money-weighterate of return is most likely:A.less ththe time-weighterate of return. B.the same the time-weighterate of return. C.greater ththe time-weighterate of return.A is correct. The money-weighterate of return is founsetting the present value (PV) of investments into the funequto the PV of the funs terminvalue. Because most of the investment came ring Ye2, the measure will biasetowarthe performanof Ye2. Set the PV of investments equto the PV of the funs terminvalue: 10+1001+r=10×1.14×1.08+100×1.08(1+r)210+\frac{100}{1+r}=\frac{10\times1.14\times1.08+100\times1.08}{{(1+r)}^2}10+1+r100=(1+r)210×1.14×1.08+100×1.08 Solving for r results in r = 8.53%.
