2). The five alternatives are being evaluated by the rate of return method, using the following information: Initial investments Individual ROR Rate ofReturn.% Incremental RoR, %, when compared with alternative V WX YZ Alternative - 27.3 19.4 35.3 25.0 -25,000 35,000 40,000 -60,000 -75,000 9.6 15.1 13.4 25.4 20.2 - 0.0 38.5 24.4 -46.5 27.3 .6.8 If the alternatives are independent and MARR-20% per year, which alternative (s) should be selected?
