Consider the following projects, X and Y where the firm can only choose one. Project X costs $$1500$ and has cash flows of $$678,$ $$652,$ $$347,$ $$111,$ $$54,$ $$16$ in each of the next $6$ years. Project Y also costs $$1500,$ and generates cash flows of $$738,$ $$693,$ $$405$ for the next $3$ years, respectively. WACC$=9\mathrm{.}5\%.$

A$)$ Draw the timelines for both projects: X and Y$.$

B$)$ Calculate the projects$$ NPVs$,$ IRRs, payback periods.

C$)$ If the two projects are independent, which project$($s$)$ should be chosen?

D$)$ If the two projects are mutually exclusive, which projects should be chosen?

E$)$ Plot NPV profiles for the two projects. Identify the projects$$ IRRs on the graph.

F$)$ If the WACC were $5\mathrm{.}5$ percent, would this change your recommendation if the projects were mutually exclusive? If the WACC were $16\mathrm{.}5$ percent, would this change your recommendation? Explain your answers.

G$)$ There is a $$crossover rate$$ of X$$s and Y$$s NPV curves, and mark it on the graph with Point O$.$ Explain in words what this rate is and how it affects the choice between mutually exclusive projects.

H$)$ Is it possible for conflicts to exist between the NPV and the IRR when independent projects are being evaluated? Explain your answer.

Hello, I have been able to figure out parts A$-$D$,$ but would really appriciate some guidance with E$-$H$.$ Thank you so much in advanced!
