This assignment solution addresses key concepts in business finance, focusing on investment appraisal techniques and time deposits. The solution begins by defining and comparing various investment appraisal methods such as payback period, Internal Rate of Return (IRR), Profitability Index (PI), and Net Present Value (NPV), evaluating their strengths and weaknesses. It then explores the practical challenges in applying these techniques, particularly in making reliable cash flow projections and determining appropriate discount rates. The solution also provides a comparative analysis of two time deposit options offered by different banks, calculating the maturity values and recommending the more profitable investment based on the provided interest rates and compounding periods. The assignment references relevant financial literature to support the analysis.
