Consider the following 5-years investment table of Agus's cash flow with required return rate j=11% (RRR). Discounted is a discount factor based on RRR. Contribution is amount of money that Agus paid to start the business (investment). Whereas, return is amount of money that Agus received from the investment. Furthermore, PV Contrib is present value of Contribution based on RRR, then Net Cash Flow is Return minus Contribution. Moreover, Discounted Cash Flow is present value of Net Cash Flow based on RRR. Finally, NPV at year "4" is NPV of investment from now (t=0) until year "Y". If t=5 then the investment has settled or matured.

Calculate the Profitability Index of this investment under required return rate. (b). Find the discounted payback period over this investment under required return rate. (c). From the cash flow of contribution and return, Agus knew that this investment will yield an internal return rate (IRR = 0.172894062). Based on modified internal return rate (MIRR), what can you conclude from Agus's investment? Please give a comment to analyze this investment. Show your work to produce the equated value of modified NPV under MIRR method. Hint: You have to look for theory of Profitability Index, Discounted Payback Period, and MIRR. For Profitability Index (PI) = NPV/I and it's computed under RRR (1). For Discounted Payback Period, find the minimum k for which NPV until k-year is positive under RRR (). For MIRR method, you must show that present value of Return under IRR is greater than the present value of Contribution under RRR. State your comment and conclusion from your work especially in MIRR
