Difficulty: Easy
Correct Answer: 12
Explanation:
Introduction / Context:
This problem checks direct left-to-right indexing in the 26-letter English alphabet. Knowing the immediate positions of common letters accelerates many reasoning questions that stack multiple letter operations.
Given Data / Assumptions:
Concept / Approach:
Count sequentially or recall standard anchor points (e.g., J=10, K=11, L=12) used widely in coding and puzzles.
Step-by-Step Solution:
Verification / Alternative check:
Cross-check with R = 27 - L formula if needed: If L=12, then from right R=15; indeed, counting backward from Z yields L at the 15th position from the right, consistent.
Why Other Options Are Wrong:
Values 16, 11, 15, 13 do not match the fixed sequence position for L.
Common Pitfalls:
Off-by-one errors due to hurried counting; using known anchors (J=10, L=12) prevents slips.
Final Answer:
12
