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?
