Reverse alphabetical order coding
Question
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?
Options
OGXPMLD
OGXQMLE
OFXPMLE
OFXPMLD
Explanation
Reversing the English alphabet means A (1) maps to Z (26), B (2) maps to Y (25), etc. The mathematical rule for reverse alphabetical mapping is: ⟨MATH⟩New Position = 27 - Original Position⟨/MATH⟩.
Apply this to the letters of `LUCKNOW`:
Concatenating these letters yields `OFXPMLD`.
