Ranking test – convert right-rank to left-rank: Rashmi is 14th from the right end in a row of 40 girls. What is Rashmi's position from the left end?

Introduction / Context:Left/right rank conversions rely on a single identity relating total count and positions from either end. This problem checks that formula and careful substitution.

Given Data / Assumptions:

• Total girls N = 40.
• Rashmi's rank from the right = 14.
• All are in a single straight line; no gaps/duplicates.

Concept / Approach:Use the conversion: position_from_left = N − position_from_right + 1. This counts how many stand before her from the left side.

Step-by-Step Solution:

Verification / Alternative check:If she is 14th from the right, there are 13 to her right and therefore 40 − 13 − 1 = 26 to her left; counting Rashmi gives 27th from left—consistent.

Why Other Options Are Wrong:Values like 25th or 26th come from forgetting the “+1” term; “21th” miscalculates the gap.

Common Pitfalls:Dropping the “+1,” or confusing direction (left vs right) especially under time pressure.

Final Answer:27th
