Consider the following project data. Assume costs are incurred upon completion of an activity. At the end of the project a lump sum payment of 340,000 is to be made.
a) Find the net present value of the project at a discount rate of 3% per period.
| Activity | Crashed Duration | Normal Duration | Crashed Cost | Normal Cost |
| C | 5 | 7 | 22000 | 18000 |
| E | 11 | 14 | 58000 | 46000 |
| I | 8 | 10 | 44000 | 36000 |
b)Given an option is available to reduce the duration of following activities at additional cost, what would be the optimal project duration? Assume indirect costs to be negligible.
