问题如下：
An investment will provide cash flows to investors as folloing pattern
$20 in Year 1, -$10 in Year 2, $10 in Year 3, and then send back $100 principal at the end of Year 4.
Assume the discount rate is 8%. Calculate the present value of the investment:
选项：
A.$91.39.
B.$108.29.
C.$135.58.
解释：
A is correct.
CF0 = 0; CF1 = 20; CF2 = -10; CF3 =10; CF4 = 100; I/Y = 8;
NPV= $91.39.
老师，send back $100 principal 是什么意思？又投了100吗？
这个问题不用回答啦刚没仔细读题，有另外个问题：投资者最初是不是应该有个100的本金投入啊，虽然题中没说，但是感觉怪怪的，因为最后有个本金的返还
$108.29. $135.58. A is correct. CF0 = 0; CF1 = 20; CF2 = -10; CF3 =10; CF4 = 100; I/Y = 8; NPV= $91.39.请问Npv的计算怎的按计算器
$108.29. $135.58. A is correct. CF0 = 0; CF1 = 20; CF2 = -10; CF3 =10; CF4 = 100; I/Y = 8; NPV= $91.39.请问NPV的知识点在哪里出现的？
NO.PZ2015120604000008 $108.29. $135.58. A is correct. CF0 = 0; CF1 = 20; CF2 = -10; CF3 =10; CF4 = 100; I/Y = 8; NPV= $91.39. 如何判断现金流从第几期开始
NO.PZ2015120604000008 20/（1+8%）+ -10/（1+8%）^2 +10/(1+8%)^3+100/(1+8%)^4 因为每期的现金流不相等 所以不能这样计算是吗？
$108.29. $135.58. A is correct. CF0 = 0; CF1 = 20; CF2 = -10; CF3 =10; CF4 = 100; I/Y = 8; NPV= $91.39.请问这是R6里面的哪个知识点呢？
