Answer:
4.72 years
0 years (The amount invested isn't recovered)
Step-by-step explanation:
Discounted payback calculates how long it takes the amount invested in a project to be recovered from the cumulative cash flows .
For project Y, the discounted cash flows are:
Year 1 = 10,256.41
Year 2 = 4,269.20
Year 3 = 3,746.22
Year 4 = 1,067.30
Year 5 = 912.22
In year 1, 20,000 - 10,256.41 = 9,743.59 is recovered
In year 2 , 9,743.59 - 4,269.20 = 5,474.39
In year 3, 5,474.39 - 3,746.22 = 1,728.17
In year 4 , 1,728.17 - 1,067.30 = 660.87
In year 5 , 660.87 / 912.22 = 0.72
It takes 4.72 years For the amount invested to be recovered.
For project Z, the discounted cash flows are:
In year 1 = 8,547.01
In year 2 = 7,305.14
Total discounted cash flows is 15,852.15
The amount invested isn't recovered
