There are four mutually exclusive projects D$1,$ D$2,$ D$3,$ and D$4$ whose IRR on incremental investment between the projects is given as follows:

IRR$($D$1-$D$2)=27\mathrm{.}62\%$

IRR$($D$1-$D$3)=14\mathrm{.}26\%$

IRR$($D$1-$D$4)=25\mathrm{.}24\%$

IRR$($D$3-$D$2)=30\mathrm{.}24\%$

IRR$($D$2-$D$4)=17\mathrm{.}24\%$

IRR$($D$3-$D$4)=16\mathrm{.}14\%$

Describe clearly the principle and how you would use it to select the best project in light of the company$$s MARR of $15\%$
