Which оf the fоllоwing stаtements аbout net present vаlue (NPV) are correct? I. The NPV of a project decreases as the required rate of return increases, all else equal.II. When a project’s internal rate of return equals the required rate of return, its NPV is zero.III. The NPV rule can be used to evaluate mutually exclusive projects.IV. NPV is not affected by the timing of cash flows if the total amount received is the same.
