Understanding the Code Language Pattern

The problem describes a specific code language where words are transformed into coded forms based on a hidden pattern. We are given two examples: 'ABASE' is coded as 'ZEZVD' and 'BANDS' is coded as 'EZQGV'. Our goal is to decipher this pattern and apply it to code the word 'CABIN'.

Analyzing the Given Examples

Let's look at the transformation of each letter in the given examples:

Example 1: ABASE → ZEZVD

• A → Z
• B → E
• A → Z
• S → V
• E → D

Example 2: BANDS → EZQGV

• B → E
• A → Z
• N → Q
• D → G
• S → V

Identifying the Coding Logic

Let's examine the shift in alphabetical positions for each letter. Remember A=1, B=2, ..., Z=26.

By comparing the shifts, we can observe a pattern related to whether the original letter is a vowel (A, E, I, O, U) or a consonant:

• Vowels (A, E): They are shifted back by one position ($\text{-1}$). When A is shifted back by 1, it wraps around to Z.
• Consonants (B, S, N, D): They are shifted forward by three positions ($\text{+3}$).

This vowel/consonant coding pattern is consistent across both 'ABASE' and 'BANDS'.

Coding the Word 'CABIN'

Now, let's apply this pattern to the word 'CABIN'. We will go through each letter:

• C: C is a consonant. Consonants are shifted by $\text{+3}$. C $\xrightarrow{\text{+3}}$ F.
• A: A is a vowel. Vowels are shifted by $\text{-1}$. A $\xrightarrow{\text{-1}}$ Z.
• B: B is a consonant. Consonants are shifted by $\text{+3}$. B $\xrightarrow{\text{+3}}$ E.
• I: I is a vowel. Vowels are shifted by $\text{-1}$. I $\xrightarrow{\text{-1}}$ H.
• N: N is a consonant. Consonants are shifted by $\text{+3}$. N $\xrightarrow{\text{+3}}$ Q.

Combining the coded letters, 'CABIN' is coded as 'FZEHQ'.

Conclusion

Based on the established vowel/consonant coding pattern from 'ABASE' and 'BANDS', the word 'CABIN' is coded as 'FZEHQ'.

Additional Information on Letter Coding

Letter coding is a common type of question in logical reasoning and coding-decoding sections of competitive exams. These patterns can vary widely but often involve:

• Shifting positions (like +1, -2, +3, etc.)
• Alternating shifts
• Grouping letters (vowels/consonants, first half/second half of alphabet)
• Reversing the order of letters
• Substitution with opposite letters (A with Z, B with Y, etc.)
• Combining multiple rules

Practicing different types of letter coding problems helps in quickly identifying the pattern during the exam.
