PMI Agile Certification Practitioner(PMI ACP) Exam Practice Test 3

The correct answer is that IRR (Internal Rate of Revenue) is most like the concept of interest earned on a savings account. The other choices are incorrect because IRR is defined as the discount rate at which project revenue equals project costs; the other choices don’t define IRR. In addition, IRR can’t be directly compared to NPV because NPV is not a ratio, it’s a total value at a point in time.
