This report provides a comprehensive financial analysis for business decision-making. It begins with an evaluation of two investment models, Dysn and Texla, using the payback period, ARR, NPV, and IRR methods. The analysis includes detailed calculations for each model, highlighting the advantages and disadvantages of each financial metric. Based on the analysis, the report recommends investing in Dysn: Model 1 due to its higher NPV, IRR, ARR, and shorter payback period. The report also examines financial ratios, focusing on Tesco's performance, including gross margin, net margin, current ratio, quick ratio, debt-to-equity ratio, total debt to total assets, asset turnover, and inventory turnover. It explores the advantages and disadvantages of financial ratio analysis and identifies potential limitations such as reliance on historical data, the impact of accounting practices, and the inability to predict future events. The report concludes that while financial ratio analysis is a valuable tool, its limitations should be considered for a complete understanding of a company's financial health and decision-making process.
