Answer:
NPV 501.54
benefit-cost ratio: 1.0066872
Explanation:
discount rate 0.2
[tex]\frac{Maturity}{(1 + rate)^{time} } = PV[/tex]
[tex]\frac{20000}{(1 + 0.2)^{1} } = PV[/tex]
[tex]\frac{25000}{(1 + 0.2)^{2} } = PV[/tex]
[tex]\frac{30000}{(1 + 0.2)^{3} } = PV[/tex]
[tex]\frac{50000}{(1 + 0.2)^{4} } = PV[/tex]
# Cashflow Discounted
0 -75000 -75000
1 20000 16666.67
2 25000 17361.11
3 30000 17361.11
4 50000 24112.65
NPV 501.54
PV ratio of the project: PV of cashflow / PV of outflow
75,501.54/75,000 = 1,0066872
