    Hi Mr. John
    I find this question quite tricky. I understand the definition of IRR is the rate at which NPV is zero and I understand the calculation in this question but I do not arrive at zero if you know what I mean. Please be kind enough and explain this question to me detail.

    A machine has an investment cost of $60,000 at time 0. The present values (at time 0) of the expected net cash inflows from the machine over its useful life are:

    Discount rate Present value of cash inflows
    10% $64,600
    15% $58,200
    20% $52,100

    What is the internal rate of return (IRR) of the machine investment?

    A Below 10%
    B Between 10% and 15%
    C Between 15% and 20%
    D Over 20%

    The NPV at 10% is +$4,600, at 15% is – $1,800 (and at 20% is – $7,900, but this is irrelevant),

    For an NPV of zero the IRR must therefore be somewhere between 10% and 15%.
