How does cash flow affect the evaluation of an investment? If an initial investment will be $100,000, which is better, a one-time return of $120,000 received in one year after the investment is made, or a return of $10,000 every month for that one year?

I am trying to learn how to do this. Please show how the PV is determined for both alternates. And explain how cash flow affects the evaluation of the investement.
