Answer:
If the company start the project today then NPV of the project,
Year Cash Flow PV of Cash flow
0 -490 -490
1 365 365/1.09= 334.86
2 365 365/1.09^2 = 307.21
3 365 365/1.09^3= 281.85
NPV = 433.92
NPV of Project0= $ 433.92
If a company start a project after one year,
Year Cash Flow PV of Cash flow
0 0 0
1 -530 -530/1.09= -486.24
2 405 405/1.09^2 =340.88
3 405 405/1.09^3 = 312.73
4 405 405/1.09^4 = 286.91
NPV = 454.28
NPV of Project1= $ 454.28
Here for project start after one year has more Net Present Value of cash flow compared to which start now.
So, Starting a project after one year is more profitable.
