Answer:
a)Project 2 should be selected
b) Project 1 should be selected
Explanation:
We would compute the Present Value(PV) of the cash inflows from the the two projects and compare them.
PV of cash inflow = A × (1- (1+r)^(-n)/r
A-cash inflow, r- required return, n - number of years
Project A = 52,000× (1 - 1.15^(-6)/0.15= 196,793.1
Project 2= 39,000 + ((1 - 1.15^-7)/0.15= 201,256.36
Project 2 should be selected
Project 1 = 52,000× (1 - 1.12^(-6)/0.15=213,793.1808
Project 2= 39,000 + ((1 - 1.12^-8)/0.15= 193,737.9509
Project 1 should be selected
