The Correct Option is D
Solution and Explanation
Concept:
Logical sequencing problems require placing elements into a timeline based on constraints.
Step 1: Mapping the timeline.
Days: Tue, Wed, Thu, Fri, Sat. Constraints: 1. Sameer - Nayan (Sameer plays, then Nayan next). 2. Ajay _ _ Sameer (or Sameer _ _ Ajay). 3. Vijay - Mohit (Vijay plays, then Mohit next).
Step 2: Arranging constraints.
- If Ajay is Tue, Sameer is Fri. Nayan is Sat. (Fails Vijay-Mohit condition). - If Sameer is Tue, Nayan is Wed. Ajay is Fri. Vijay is Thu, Mohit is Fri (Impossible). - Let's try: Ajay=Tue, Vijay=Wed, Mohit=Thu, Sameer=Fri, Nayan=Sat. equation Saturday Player = Nayan equation *(Self-Correction: Verify constraints. Ajay(Tue) ... Sameer(Fri)? Yes, two between them. Nayan plays after Sameer? Yes, Sat. Vijay plays before Mohit? If Vijay=Wed, Mohit=Thu. Yes. Correct!)* center Nayan center
