An analysist gathered the following about the performance of a porfolio:

 quater  value at beginning of quarter  cash inflow(ourflow) at begging of quarter  value at end of quarter

   1                  2.0                                                0.2                                         2.4

   2                  2.4                                               0.4                                          2.6  

   3                 2.6                                               (0.2)                                        3.2

   4                3.2                                                1.0                                          4.1

the porfolio's annual time-weighted rate of the return  is clised to:

答案是这样的：1.0909*0.9286*1.3333*0.9762=1.3185  1.3185-1=0.3185

请教一下：我不太能看懂它的计算谁能帮考解释一下啊？谢谢啦~~~~~
