need help with question 29 and 30

Scott Enterprises is considering a project that has the following cash flow and cost of capital ( r ) data. What is th project's NPV? Note that if a project's expected NPV is negative, it should be rejected. \begin{tabular}{|r|} \hline$194.66 \\ \hline$196.73 \\ \hline$177.49 \\ \hline$181.56 \\ \hline$190.15 \\ \hline \end{tabular} Current Design Co. is considering two mutually exclusive, equally risky, and not repeatable projects, S and L. Their cash flows are shown below. The CEO believes the IRR is the best selection criterion, while the CFO advocates the NPV. If the decision is made by choosing the project with the higher IRR rather than the one with the higher NPV, how much, if any, value will be forgone, i.e., what's the chosen NPV versus the maximum possible NPV? Note that (1) "true value" is measured by NPV, and (2) under some conditions the choice of IRR v5. NPV will have no effect on the value gained or lost
