Answer:
Internal rate of return = 16.3%
Step-by-step explanation:
The IRR is the discount rate that equates the present value of cash inflows to that of cash outflows. At the IRR, the Net Present Value (NPV) of a project is equal to zero
If the IRR greater than the required rate of return , we accept the project for implementation
If the IRR is less than that the required rate , we reject the project for implementation
IRR = a% + ( NPVa/(NPVa + NPVb)× (b-a)%
Step 1 : Calculate NPVa at 10%
NPV = PV of cash inflow - Initial cost
PV of cash inflow = 1500× ( 1- 1.1^(-2))/0.1=2,603.31
PV of salvage value = 800× 1.1^(-2) =661.16
NPV = 2,603.31 + 6,661.16 - 3000= 264.46
Step 2 :Calculate NPVb at 20%
PV of cash inflow = 1500× ( 1- 1.2^(-2))/0.2=2291.67
PV of salvage value = 800× 1.2^(-2) =555.56
NPV =2291.67 + 555.56 - 3,000 = -152.78
Step 3 : Calculate IRR
IRR = 10% + (264.46/(264.46+152.78))× (20-10)%= 16.3%
Internal rate of return = 16.3%
