If in a certain code the word "DAUGHTER" is written as "TERDAUGH" by moving the last three letters to the front, then how will "APTITUDE" be written using the same operation?

Difficulty: Easy

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
