why is for the calculation of NPV various methods are used? like sometimes it is like the NPV of a project is determined by dividing the given cash flows for the year by given WACC whereas on the contrary, NPV is calculated by multiplying the given cash flows with present value factors? this sounds a bit crazy as well but i am confused. so can you please explain this?

The table below provides the NPVS for projects A and B for a range of different discount rates: > NPV calculations: inde diecount Project A: NPV-100+70/(1.10) + 50/(1.10)2 20(1.10)2 = $19.98 Project B: NPV=-100+ 10/(1.10) + 60/(1.10)2+80/L1.10)$18.79 Accept both projects A and B if they were independent as they both have positive NPVS Accept project A over project B.if they.are mutually exclusive, as project A has a higher NPV than project B IRR calculations using trial and - Project A: IRR 23.56% - Project B: IRR 18.13% Accept both projects if they are independent as the IRR > WACC (10% ) Accept project A over project B if they are mutually exclusive, WACC NPV for Project A NPV for Project B $40.00 $50,00 5 $29.29 $33.05 error: 10 $19.98 $18.79 15 $11.83 $6.67 20 $4.63 $3.70 as project A has 3.11 higher IRR FINANCIAL MANAGEMENT (FIN5FMA) SOLUTIONS FOR TUTORIAL 3 Question 1 A firm with a 14% WACC is evaluating two projects for this year's capital budget.
