Row facing South — who sits at the extreme right end? Five friends face South. Mohan is between Balu and Raju. Raju is to the immediate right of Praveen. Amith is to the right of Balu. Who occupies the extreme right end of the row (as viewed)?

Introduction / Context:
Facing South reverses individual left/right relationships relative to our left-to-right view. We must still report the extreme right end as seen by the observer.

Given Data / Assumptions:

• “Raju is to the immediate right of Praveen.” Facing South ⇒ in our left→right drawing, Raju sits immediately left of Praveen.
• “Mohan is between Balu and Raju.” So either Balu – Mohan – Raju or Raju – Mohan – Balu (in our left→right order).
• “Amith is to the right of Balu” (our left→right sense).

Concept / Approach:
Place the adjacent pair (Raju, Praveen) as Raju–Praveen. Fit Mohan between Balu and Raju. Then push Amith to the right of Balu and locate the rightmost slot.

Step-by-Step Solution:
One valid arrangement (left→right): Raju, Praveen, Balu, Mohan, Amith.Checks: Raju immediately left of Praveen ✔ (i.e., right of Praveen when facing South); Mohan between Balu and Raju ✔; Amith right of Balu ✔.Hence the extreme right position is occupied by Amith.

Verification / Alternative check:
Any equivalent re-placement that honors the clues still yields Amith at the rightmost end.

Why Other Options Are Wrong:
Balu/Praveen/Mohan are interior under these constraints and cannot be the extreme rightmost.

Final Answer:
Amith
