IRR vs$.$ NPV Highflier has two possible mutually exclusive projects to consider. The cash flows are as follows:

$\backslash$table$[[$Year$,$Project A $(\text{'}000),$Project B $(000)],[0,-420,-100],[1,150,75],[2,150,75],[3,150,0],[4,150,0]]$

Highflier's cost of capital is $12$ per cent. Assume unlimited funds. These are the only cash flows associated with the projects.

Calculate the internal rate of return $($IRR$)$ for each project

Calculate the net present value $($NPV$)$ for each project

Compare and explain the results in $($a$)$ and $($b$)$ and indicate which project the company should undertake and why.
