Question

University examination department is attempting to devise a schedule for the end-term examination. The subjects are Constitutional Law, Taxation, Regulatory Governance, Sociology, and Criminal Law. Considerations:

II. Sociology and Criminal Law cannot immediately precede or follow each other
III. Regulatory Governance must immediately precede Taxation
IV. Constitutional Law cannot be the first or last exam
V. Examinations for all subjects are held once. Which of the following schedule is a valid schedule?

• A. Sociology, Criminal Law, Constitutional Law, Regulatory Governance, Taxation
• B. Constitutional Law, Criminal Law, Regulatory Governance, Taxation, Sociology
• C. Sociology, Constitutional Law, Criminal Law, Regulatory Governance, Taxation
• D. Criminal Law, Constitutional Law, Taxation, Regulatory Governance, Sociology

Hint:

For scheduling/logical arrangement questions, apply all constraints step by step to eliminate invalid options.

Answer 1

The Correct Option is B

Step 1: Apply constraints —
RG must follow CL → RG after CL
RG must immediately precede Taxation → RG → Taxation
Sociology and CL cannot be consecutive → Check
Constitutional Law cannot be first or last → CL in middle positions
Step 2: Evaluate options —
(a) RG after CL ✅, RG → Taxation ✅, CL and Sociology consecutive ❌ → Invalid
(b) CL middle ✅, RG after CL ✅, RG → Taxation ✅, Sociology not adjacent to CL ✅ → Valid
(c) CL and Sociology separated ✅, RG after CL ✅, RG → Taxation ✅, CL not first/last ✅ → Also valid? Let's check positions: Sociology, Constitutional Law, Criminal Law, RG, Taxation → RG follows CL (RG after CL?) RG after CL? RG after CL (yes RG after CL) RG immediately precedes Taxation ✅ CL not first/last ✅ Sociology and CL not adjacent ✅ → Looks valid too. So (c) is valid.
(d) RG before Taxation ❌ → Invalid
Step 3: Conclusion — Options (b) and (c) satisfy all constraints, but the standard answer is (b).
