Understanding the Code Transformation
To decode the transformation from 'CRACKJACK' to 'XIZXPQZXP', we need to analyze the pattern of letter substitution.
Step-by-Step Breakdown
1. Letter Positioning:
Each letter in the word 'CRACKJACK' corresponds to a letter in 'XIZXPQZXP'. We will examine the relationship between the letters.
2. Substitution Pattern:
- C → X
- R → I
- A → Z
- C → X
- K → P
- J → Q
- A → Z
- C → X
- K → P
The transformation appears to follow a specific pattern, where letters are shifted a certain number of positions in the alphabet.
3. Shift Calculation:
Upon inspection, we can identify that each letter in 'CRACKJACK' is replaced by a letter that is a fixed number of positions down the alphabet. The transformations can be summarized as follows:
- C shifts to X (C + 21)
- R shifts to I (R + 9)
- A shifts to Z (A + 25)
- K shifts to P (K + 5)
- J shifts to Q (J + 7)
Applying the Same Logic to 'HAPPYBOYS'
Now, we will apply the same letter shifting to 'HAPPYBOYS' to find its code:
- H → S (H + 11)
- A → Z (A + 25)
- P → K (P + 5)
- P → K (P + 5)
- Y → B (Y + 5)
- B → L (B + 10)
- O → Y (O + 10)
- Y → B (Y + 5)
- S → H (S + 1)
Combining these, we get: SZKKBYLBH.
Conclusion
Thus, the code for 'HAPPYBOYS' is 'SZKKBYLBH'. The correct answer is option C.
