Draw an activity network and find the critical path for a research project given below.


There are eight tasks in a small project. Task A takes 14 days to complete. Task B takes 16 days to complete and can be executed in parallel with Task C which takes 22 days to complete. When tasks B and C are completed, task D can be executed which will take 17 days to complete. When D is completed, tasks E and F can be executed which will take 13 and 10 days to complete. When tasks E and F are completed, task G can be executed which will take 15 days to complete.
