Question

In a certain language
ABCD is coded as CABF 
FGHI is coded as HFGK |
UVWX is coded as WUVZ 
How is KLMN coded?

• A. KLMP
• B. MKLP
• C. MNOP
• D. MNPO

Answer 1

The Correct Option is B

To decode the pattern used in the given language, we need to analyze each example provided:

1. Consider the first example: ABCD → CABF. The pattern here is:
   • The first letter 'A' becomes the third letter 'C' in the code.
   • The second letter 'B' moves to the fourth position.
   • The third letter 'C' becomes the first letter.
   • The fourth letter 'D' becomes the second letter, plus one position forward in the alphabet (D → F).
2. For the second example: FGHI → HFGK.
   • The first letter 'F' becomes the third letter 'H'.
   • The second letter 'G' is placed in the fourth position.
   • The third letter 'H' becomes the first letter.
   • The fourth letter 'I' becomes the second letter and moves one position forward as I → K.
3. For the third example: UVWX → WUVZ.
   • The first letter 'U' becomes the third letter 'W'.
   • The second letter 'V' is now in the fourth position.
   • The third letter 'W' is placed as the first.
   • The fourth letter 'X' becomes the second letter and is updated to the next alphabet letter as X → Z.

From these patterns, the encoding of letters follows two key observations:

• The first three letters are rearranged as 3rd-1st-4th.
• The fourth letter in the sequence is moved one position forward alphabetically to get the last character in the code.

Now, applying the same pattern to KLMN:

• The first letter 'K' becomes the third letter 'M'.
• The second letter 'L' becomes the fourth letter.
• The third letter 'M' becomes the first letter.
• The fourth letter 'N' becomes the second letter and advances one position alphabetically from N to P.

Thus, KLMN is coded as MKLP.

Therefore, the correct answer is: MKLP.
