If in a certain language, PUBLIC is coded as KFYORX, then how is 'SERVANT' coded in that language?
Answer & explanation
Correct answer: option 3
The correct answer is Option (3) → HVIEZMG
The rule is read off the given word first. In PUBLIC → KFYORX, each letter is replaced by its opposite letter, the letter in the same place counted from the other end of the alphabet. A letter and its opposite have positions that add up to 27.
P (16) → K (11), U (21) → F (6), B (2) → Y (25)
L (12) → O (15), I (9) → R (18), C (3) → X (24)
The same rule on SERVANT:
S (19) → H (8), E (5) → V (22), R (18) → I (9), V (22) → E (5)
A (1) → Z (26), N (14) → M (13), T (20) → G (7)
SERVANT is coded as HVIEZMG
Tip: The opposite pairs can be learnt as two halves of the alphabet: A to M written above N to Z in reverse (A–Z, B–Y, C–X, …, M–N), so each letter’s partner is found at a glance.
