问题如下：

A firm is planning to construct a $ 10,000 production line. Assume the cost of capital is 10% and the plan's useful life is 4 years, given the cash flows for this plan:

Which of the following statements about the plan is least likely correct?

选项：

The discounted payback period is 2.33 years.

The NPV of the project is +$1,471.21; accept the project.

The IRR of the project is17.80%; accept the project.

解释：

A is correct.

$CF_0=-10,000$

$PVCF_1=\frac{5,000}{1.10}=4,545.45\;\;$

$PVCF_2=\frac{4,000}{1.10^2}=3,305.79$

$PVCF_3=\frac{3,000}{1.10^3}=2,253.94$

$PVCF_4=\frac{2,000}{1.10^4}=1,366.03$

CF after year 2 = -10,000+4545.45+3305.79= -2148.76

2148.76/2253.94=0.9533

So, the discounted payback period of 2.95 years.
