Answer: B. The ROI percentages
Explanation: Making comparison between investments in terms of returns will involve calculating the ROI as a percentage. The ROI refers to the return on an investment which is the ratio of the net profit made from an investment and the cost of the investment. That is ;
ROI = (Net profit / cost of investment) × 100
Investment with greater or higher return on investment (ROI) is usually regarded as the best investment between alternatives. For instance two investments, A and B with ROI of 5% and 10% respectively. Investment B has a higher ROI than A and thus considered has the better investment decision.
