Can you please help me here? Even a hypothetical situation is much appreciated.

You need to select a small firm. This could be start-up or existing business planning for investment (Capex). Interview the person to assess the investment lay out (investment in various assets). Discuss with him, revenue, cost (COGS and Opex), growth rate, tentative life of assets. Based on this information, project the cash flows for the project's life. Considering cost of capital to be 10%, compute NPV of the project. Also, compute IRR of project. Suggest whether investment plan should be accepted or not
