Assume that the required return of Silicon Co. is 6%.

a) Calculate payback period of the two projects. Which project should the company choose? Explain your answer. (4 marks)

b) Suggest 2 reasons to explain why payback period may not be a good method to evaluate the two projects for Silicon Co. (6 marks)

c) Calculate discount payback period of the two projects. Which project should the company choose? Explain your answer. (7 marks)
