问题如下：
An investment of $150,000 is expected to generate an after-tax cash flow of $100,000 in one year and another $120,000 in two years. The cost of capital is 10 percent. What is the internal rate of return ?
选项：
A. 28.39 percent.
B. 28.59 percent.
C. 28.79 percent.
解释：
C is correct.
The IRR can be found using a financial calculator or with trial and error. Using trial and error, the total PV is equal to zero if the discount rate is 28.79 percent.
A more precise IRR of 28.7854 percent has a total PV closer to zero.
