Answer:
The project A has a smaller IRR, and the project B is more attractive
Explanation:
Solution
Solve for Project A:
Now,
Let assume that the IRR be x
Hence,
The  Present Value of  Outflows of Cash Outflows= The Present Value of Inflows of Cash
Thus,
2000 =500/(1.0x) +500/ (1.0x)^2 +1200/(1.0x)^3 Â Â
Or  we say x= 4.223%
Therefore the IRR is 4.223%
For project B:
Let assume that the IRR Â be y.
Thus,
The  Present Value of  Outflow of Cash = The Present Value of Inflow of Cash
so,
2000 =600/(1.0y) + 600/ (1.0y)^2 Â + 1000/(1.0y)^3
Or  we say, y= 4.498%
Therefore  the IRR is 4.498%
