In a code language, 'WINDOW' is written as 'DRMWLD', how can 'UPDATE' be written in that code?
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → FKWZGV
Each letter is replaced by its opposite letter in the alphabet (A with Z, B with Y and so on), whose place numbers add up to 27.
The rule on WINDOW:
W (23) → D (4), I (9) → R (18), N (14) → M (13)
D (4) → W (23), O (15) → L (12), W (23) → D (4), giving DRMWLD
The same rule on UPDATE:
U (21) → F (6), P (16) → K (11), D (4) → W (23)
A (1) → Z (26), T (20) → G (7), E (5) → V (22), giving FKWZGV
Tip: When the code of a letter and the letter itself have place numbers adding up to 27, the code is the opposite letter. The pairs A-Z, B-Y, C-X, ... M-N are worth knowing by heart.
