Answer:
The answer is C: 11%
Workings for NPVs are attached.
Explanation:
What Is Internal Rate of Return – IRR?
The internal rate of return (IRR) is a metric used in capital budgeting to estimate the profitability of potential investments. The internal rate of return is a discount rate that makes the net present value (NPV) of all cash flows from a particular project equal to zero. IRR calculations rely on the same formula as NPV does.
<u>Tip:</u>
To calculate the IRR we need to perform a hit and trial method - rule of thumb is, use the discount factor, that give one positive and one negative NPV, suppose, if 10% discount factor gives a positive NPV, we should choose the second discount factor that is above 10%, so the cost of investment will be high and thus giving us a negative NPV.
<u>IRR calculations:</u>
<u>Key metrix used:</u>
Discount factor (rₐ) = 10% (lowest discount factor)
NPV at lowest discount factor = 51,608
Discount factor (rb) = 15% (highest discount factor)
NPV at highest discount factor = - 161,000
<u>IRR Formula:</u>
IRR Formula = rₐ + × (rb - ra)
IRR Formula = 10% + × (15% - 10%)
IRR Formula = 11%
