The total completion time is 25 days. Task A is planned to take seven days. Task B is planned to take five days. Task C is planned to take eight days. The tasks have a serial relationship. Task A takes nine days to be completed instead of seven days. How much slack does the project have now that Task A is finished

Explanation:

The computation of the number of slacks in the project A when it is finished is

= Total completion time -- Task A planned days - Task B planned days - Task C planned days

= 25 days - 9 days - 5 days - 8 days

= 3 days slack    

Simply we subtract the total planned days taken by each task from the total completion time on a project so that the number of slacks has come

Therefore, it came positive 3 slacks time
