I need an answer and interpretation for these two questions

1.Following are three independent projects Peanut/ Pecan Processing (PPP) is evaluating: Project IRR RISK P 10% Low Q 12% Average R 14.5% High PPP generally considers risk when examining projects by adjusting its average required rate of return, r, which equals 11 percent. A 4 percent adjustment is made for high-risk projects, and a 2 percent adjustment is made for low-risk projects. Which project(s) should PPP purchase? 2.The CFO of Lazy Loungers is evaluating the following independent, indivisible projects: Project Cost IRR A $10,000 21.0% B 15,000 20 C 25,000 16 Lazy's weighted average cost of capital (WACC) is 14 percent if the firm does not have to issue new common equity; if new common equity is needed, its WACC is 17 percent. Lazy's capital structure consists of 40 percent debt. If Lazy has no preferred stock and expects to generate $24,000 in retained earnings this year, which project(s) should be purchased
