If the order of the letters in the English alphabet is reversed and each letter represents the letter whose position it occupies, then which one of the following represents ‘LUCKNOW’?

The correct option is OFXPMLD.

To understand why this is the correct answer, let us look at the relationship between the letters of the English alphabet and their reversed positions.

In the standard English alphabet, each letter corresponds to a specific position from 1 to 26:
A = 1, B = 2, C = 3, D = 4, E = 5, F = 6, G = 7, H = 8, I = 9, J = 10, K = 11, L = 12, M = 13, N = 14, O = 15, P = 16, Q = 17, R = 18, S = 19, T = 20, U = 21, V = 22, W = 23, X = 24, Y = 25, Z = 26.

When the alphabet is reversed, the positions are mapped from Z to A, where Z becomes 1, Y becomes 2, and so on. For any letter at position x, its position in the reversed alphabet is given by:
$\mathrm{Reversed\; Position}=27-x$

Let us find the reversed representation for each letter of the word LUCKNOW step-by-step:

1. For L (Standard position 12):
Reversed position = 27 - 12 = 15. The 15th letter is O.

2. For U (Standard position 21):
Reversed position = 27 - 21 = 6. The 6th letter is F.

3. For C (Standard position 3):
Reversed position = 27 - 3 = 24. The 24th letter is X.

4. For K (Standard position 11):
Reversed position = 27 - 11 = 16. The 16th letter is P.

5. For N (Standard position 14):
Reversed position = 27 - 14 = 13. The 13th letter is M.

6. For O (Standard position 15):
Reversed position = 27 - 15 = 12. The 12th letter is L.

7. For W (Standard position 23):
Reversed position = 27 - 23 = 4. The 4th letter is D.

Putting these letters together in order, we get OFXPMLD.
