In a certain code, 'ROAD' is written as 'SQBE'. How is 'SWAN' written in that code?
TXBO
TZBO
UXBO
TVBO
TXBO
Apply a consistent forward shift of +1 to each letter of the alphabet sequentially.
Apply a consistent forward shift of +1 to each letter of the alphabet sequentially.
Step 1: Identify the coding pattern
Each letter in the source word is shifted forward by 1 position in the English alphabet.
Step 2: Apply the shift to SWAN
1: S (+1) → T, 2: W (+1) → X, 3: A (+1) → B, 4: N (+1) → O. Combining these transformed letters gives TXBO.
B: TZBO is incorrect because the second letter is Z instead of X, C: UXBO is incorrect because the first letter is U instead of T, D: TVBO is incorrect because the second letter is V instead of X.
A is correct because shifting each letter of SWAN forward by 1 position yields TXBO.
Always verify uniform letter shifts across all characters before assuming complex alternating or vowel-consonant rules.
