Question 1
6 tasks (A, B, C, D, E, F) are to be completed one after the other. The following conditions must be met:
- Task E must be performed immediately after Task C.
- Task D must be completed before Task B.
- Task A is neither the first nor the last task to be completed.
- Task B is performed exactly 2 positions after Task F.
Which task is scheduled in the second position?
Step-by-step solution (Deductive Logic):
1. Apply Consecutive Constraint: 'E immediately after C' -> (C, E)
2. Apply Before Constraint: 'D before B'
3. Apply Exclusion Constraint: 'A not first or last'
4. Apply Gap Constraints: 'B is 2 after F'
Final Sequence: C → E → A → F → D → B
Answer: The task in the second position is E.
Key Strategy: Use fixed pairs and gap constraints to anchor positions.
