Conflicts between NPV and IRR arise when they give different accept/reject decision. The main reason for conflict is cash flows are not conventional (more than one outflow), different lives or different sizes. In our case both IRR and NPV are giving same accept/reject decision hence no conflict but when IRR and NPV given different result preference is given to NPV rule (We might also want to apply Equivalent Annuity approach)
