Start by calculating the NPV of each project as follows:
NPV(A) = (1,000) + 100 / (1.1156)1 + 250 / (1.1156)2 + 450 / (1.1156)3 + 650 / (1.1156)4 + 0 = 34.26
NPV(B) = (2,500) + 500 / (1.1156)1 + 900 / (1.1156)2 + 1200 / (1.1156)3 + 1200 / (1.1156)4 + 700 / (1.1156)5 = 715.44
NPV(C) = (1,750) + 200 / (1.1156)1 + 300 / (1.1156)2 + 600 / (1.1156)3 + 700 / (1.1156)4 + 800 / (1.1156)5 = 17.34
NPV(D) = (4,000) + 1,400 / (1.1156)1 + 1,400 / (1.1156)2 + 1,400 / (1.1156)3 + 1,400 / (1.1156)4 + 1,400 / (1.1156)5 = 1,102.18
NPV(E) = (2,000) + 300 / (1.1156)1 + 400 / (1.1156)2 + 700 / (1.1156)3 + 700 / (1.1156)4 + 700 / (1.1156)5 = (48.51)
Ranking the projects starting with the highest NPV to lowest NPV: DBACE.
