Ranking test – left/right conversion with an offset: In a row of 25 children, Nayan is 14th from the right end. Arun stands 3 places to the left of Nayan. What is Arun's position from the left end?

Difficulty: Easy

Correct Answer: 9th

Explanation:


Introduction / Context:
We first convert Nayan’s right-rank to a left-rank, then adjust for Arun being 3 to the left (which reduces the left-rank by 3), and finally confirm boundaries.



Given Data / Assumptions:

  • N = 25 children in a single row.
  • Nayan: 14th from right.
  • Arun is 3 places to the left of Nayan.


Concept / Approach:
Use left-rank = N − right-rank + 1, then subtract 3 for the leftward shift to find Arun’s left-rank.



Step-by-Step Solution:

Nayan left-rank = 25 − 14 + 1 = 12.Arun left-rank = 12 − 3 = 9.


Verification / Alternative check:
Arun is indeed further left (smaller left-rank) than Nayan; 9 is within 1…25, so it’s feasible.



Why Other Options Are Wrong:
7th/8th/10th reflect miscounting the 3-position offset or left/right conversion.



Common Pitfalls:
Adding 3 instead of subtracting when moving left on left-ranks; dropping the +1 in the initial conversion.



Final Answer:
9th
