HELP ME ANSWER THIS QUESTION,PLEASE... =)

Do you know what is payback period?

Do you know how to find the NPV of an investment given discounted rate?

For the last part, you will first have to find the NPV of each project with another discounted rate. Then with two rates and two NPVs for each, you will be able to get each one's IRR.
