Questions & Step-by-Step Solutions
In a project involving tasks A, B, C, and D, if A and B can be done simultaneously but must be completed before C, and D can be done at any time, which of the following is a correct sequence?
Step 1: Identify the tasks involved in the project: A, B, C, and D.
Step 2: Understand the relationships between the tasks: A and B can be done at the same time, but both must be finished before starting C.
Step 3: Note that task D can be done at any time, meaning it does not depend on A, B, or C.
Step 4: Determine a valid sequence of tasks. Since A and B can happen together, we can start with both A and B.
Step 5: After completing A and B, we can then proceed to task C, as it requires A and B to be finished first.
Step 6: Finally, task D can be done either before, after, or during the other tasks, but for this sequence, we will place it at the end.
