Consider two projects whose annual net cash flows are not even. Assume that each project costs R$200\mathrm{.}00.$ The net cash flows for each year are as follows:

$*$ year $1$ project M $-20000$ Project O $-100000$

$*$year $2$ Project M $-40000$ Project O $-80000$

$*$year $3$ Project M $-60000$ Project O $-60000$

$*$year $4$ Project M $-80000$ Project O $-40000$

$*$year $5$ Project M $-100000$ project O $-20000$

Calculate the payback period of each project and recommend the project that should be selected based on the payback method
