Answer
Correct Answer: UDEAPTIT
Explanation
Introduction / Context:This tests recognition of a rotation operation: relocating a fixed block of letters from the end of a word to its beginning.
Given Data / Assumptions:
- DAUGHTER -> TERDAUGH
- Operation: take the last three letters and place them at the front.
- Apply to APTITUDE.
Concept / Approach:For a word W = X Y Z where Z are the last three letters, the coded form is Z X Y.
Step-by-Step Solution:APTITUDE -> last three letters = U D E.Move UDE to front, leave the rest A P T I T unchanged.Result: UDEAPTIT.
Verification / Alternative check:Applying the inverse (moving first three to end) returns the original, confirming correctness.
Why Other Options Are Wrong:
- DEUAPTIT / DUEAPTIT: these permute the last-three block incorrectly.
- DAUEPTIT: intermixes the block with the original middle letters.
- None of these: Not needed since UDEAPTIT is valid.
Common Pitfalls:Reversing the last-three block or moving four letters by mistake.
Final Answer:UDEAPTIT
