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’?

  1. A.OGXPMLD
  2. B.OGXQMLE
  3. C.OFXPMLE
  4. D.OFXPMLD
▶ Answer & Explanation

Correct answer: D. OFXPMLD

When the English alphabet is reversed, A becomes Z, B becomes Y, and so on. This is known as reverse alphabet coding. To solve for LUCKNOW, we find the corresponding reversed letter for each letter: L maps to O, U maps to F, C maps to X, K maps to P, N maps to M, O maps to L, and W maps to D. Therefore, LUCKNOW is coded as OFXPMLD.
