Which project or projects should the company undertake? Base your results on the NPV. d) Assume that the two projects are mutually exclusive and the cost of capital is 5%. Which project or projects should the company undertake? Base your results on the MIRR. e) Explain why quantitative measures may not always be the best way to evaluate a project
