This is project planing and control question,plz answer it fully.

Using the information in the table below and the network diagram in appendix 1, determine the shortest duration that can be achieved by project crashing along with the associated project cost. Clearly demonstrate your crash analysis sequence c. (14 marks) Notes: 1. Durations given are in days 2. Indirect overhead costs of 50 per day 3. The network diagram for normal durations is given in the appendix of this paper Min Available Normal Crash Crash Normal Crash Days Activity ty PredecessorTime Time Cost Cost 150 70 20 , 150 100 180 50 60
