Answer: a). 3.55 years b). 3.90 years
c). 6 years
Explanation:a). A discount rate of 0% gives exactly the same amount when the cash flow is not discounted. For the project; cash flow of 3 years will give $2,820 × 3 =$ 8460
$10000 - $8460 = 1540
$1540/$2820 = 0.55
Therefore, discounted payback period = 3.55 years
b). At a dicount factor of 4%, the discounted cash flow will be $(2711.43 + 2607.37 + 2506.98) = $7825.78
$(10000 - 7835.78 )= 2174.22
$2174.22/$2410.54 =0.90
Therefore discounted payback period at 4% = 3.90 years
c). At a discounted rate of 19%, the cashflow per year reduces further. The discounted payback period will be 6 years. That is, $(2369.75 + 1991.38 + 1673.39 + 1406.24 + 1181.72 + 993.94) = $9615.52
