Assume for the following problems that work continues during weekends.

a. A task is planned to start on April 30 and takes 20 days to complete. The actual start date is May 3.

After 4 days of work the supervisor estimates that the task is 25 percent completed. If the work rate stays the same, what is the forecast date of completion?

b. Task C has two immediate predecessors, tasks A and B. Task A is planned to take 5 days to complete; Task B is planned to take 10 days. The early start time for both tasks is August 1.

The actual start dates for tasks A and B are August 2 and August 1, respectively. At the end of August 4, Task A is assessed to be 20 percent completed and Task B, 30 percent completed. What is the expected early start time for Task C?
