Project A and B are mutually exclusive projects. Both projects have an estimated life of three years. Calculate the cross-over rate between projects A and B (discount rate at which the NPV of both projects is same). Now assume a cost of capital percentage for these projects higher than this cross-over rate. Give your decision to accept/reject project/s and justify your answer.
