Questions & Step-by-Step Solutions

If tasks M, N, O, and P are scheduled such that M must be done before N and O, and N must be done before P, which of the following sequences is valid?
  • Step 1: Identify the tasks: M, N, O, and P.
  • Step 2: Understand the conditions: M must be done before N and O, and N must be done before P.
  • Step 3: Write down the order of tasks based on the conditions.
  • Step 4: Check if M is before N and O in the sequence.
  • Step 5: Check if N is before P in the sequence.
  • Step 6: The sequence M, N, O, P meets both conditions, so it is valid.
  • Task Scheduling – Understanding the order of tasks based on given dependencies.
  • Dependency Management – Identifying which tasks must precede others in a sequence.
