Difficulty: Medium
Correct Answer: Raju and Ram
Explanation:
Introduction / Context:
This row-arrangement puzzle specifies two tight 3-person blocks and several non-adjacency conditions. We must deduce who flanks Jose.
Given Data / Assumptions:
Concept / Approach:
Treat the two trios as blocks and place them side-by-side. Only one concatenation satisfies the non-adjacencies.
Step-by-Step Solution:
If we place [Gopi–Uday–Ram] to the left of [Jose–Raju–Manu], the touching pair is Ram–Jose (allowed), while Gopi avoids Jose/Manu and Ram avoids Manu.Any other touching (e.g., Gopi–Manu or Ram–Manu) breaks a constraint.Thus a valid full order is: Gopi – Uday – Ram – Jose – Raju – Manu.Jose’s two neighbors are Ram and Raju.
Verification / Alternative check:
Reversing the Raju-centered trio (Manu–Raju–Jose) would force Ram next to Manu at the join, which is forbidden.
Why Other Options Are Wrong:
They omit Ram or include Manu as Jose’s neighbor, violating constraints.
Common Pitfalls:
Forgetting that both Jose and Manu must flank Raju, which fixes their relative positions tightly.
Final Answer:
Raju and Ram
