Consider the following two mutually exclusive projects, each of which require an initial investment of Tk. 100,000 and have no salvage value. This organization, which has a cost of capital of 15%, must choose one or the other.

Year	Project A	Project B
1	Tk. 10,000	20,000
2	20,000	40,000
3	30,000	30,000
4	40,000	20,000
5	50,000	10,000

Compute the payback period of these two projects. Using the payback. criterion, which project is more desirable?
