Reversed alphabet indexing – If the English alphabet is written in backward order (Z to A left-to-right), which letter is 7th to the right of the letter K in that arrangement?

Introduction / Context:
With the alphabet written as Z, Y, X, …, A from left to right, “to the right of” now means movement toward the A-end (increasing the index). Correct orientation is crucial. We must find the 7th letter to the right of K in this reversed sequence.

Given Data / Assumptions:

• Reversed indexing: 1 Z, 2 Y, 3 X, 4 W, 5 V, 6 U, 7 T, 8 S, 9 R, 10 Q, 11 P, 12 O, 13 N, 14 M, 15 L, 16 K, 17 J, 18 I, 19 H, 20 G, 21 F, 22 E, 23 D, 24 C, 25 B, 26 A.
• “7th to the right” = add 7 to the reversed index.

Concept / Approach:
Find K’s reversed index: K is at position 16 in the reversed list. Move 7 positions to the right: 16 + 7 = 23. Position 23 corresponds to D in the reversed lineup above.

Step-by-Step Solution:
Index(K) in reversed = 16.16 + 7 = 23.Letter at reversed position 23 = D.

Verification / Alternative check:
Use the mapping relation between normal and reversed positions: rpos = 27 − pos. For K (normal pos=11), rpos=16. Add 7 → 23. Convert back: normal pos = 27 − 23 = 4 → D. Both methods confirm D.

Why Other Options Are Wrong:

• A/B/C/E: These correspond to other reversed positions (26/25/24/22) and do not match the required 23rd slot.

Common Pitfalls:
Moving in the wrong direction because the alphabet is reversed, or forgetting we are counting positions in the reversed sequence, not the normal one.

Final Answer:
D
