Understanding Coding Language Patterns

This question involves a coding language where words are transformed based on a specific rule or pattern. We are given an example: 'PERHAPS' is coded as 'SPAHREP'. Our task is to identify this pattern and apply it to the word 'CHEWING' to find its coded form.

Analyzing the Coding Pattern: PERHAPS to SPAHREP

Let's look at the relationship between the original word 'PERHAPS' and its coded form 'SPAHREP'. We can compare the positions of the letters:

Original Word: P E R H A P S

Positions:   1 2 3 4 5 6 7

Coded Word:   S P A H R E P

Positions:    1 2 3 4 5 6 7

Comparing the letters at each position in the original and coded words:

• The 1st letter of the original word 'P' is the last (7th) letter of the coded word 'SPAHREP'.
• The 2nd letter of the original word 'E' is the 6th letter of the coded word 'SPAHREP'.
• The 3rd letter of the original word 'R' is the 5th letter of the coded word 'SPAHREP'.
• The 4th letter of the original word 'H' is the 4th letter of the coded word 'SPAHREP'.
• The 5th letter of the original word 'A' is the 3rd letter of the coded word 'SPAHREP'.
• The 6th letter of the original word 'P' is the 2nd letter of the coded word 'SPAHREP'.
• The 7th letter of the original word 'S' is the 1st letter of the coded word 'SPAHREP'.

This shows that the letters of the original word 'PERHAPS' are simply reversed to get the coded word 'SPAHREP'. The last letter of the original word becomes the first, the second to last becomes the second, and so on.

Applying the Pattern to CHEWING

Now we apply the same reversal pattern to the word 'CHEWING'.

Original Word: C H E W I N G

Positions:    1 2 3 4 5 6 7

To reverse the word, we take the letters from last to first:

• The last letter is G. This becomes the first letter of the coded word.
• The second to last letter is N. This becomes the second letter.
• The third to last letter is I. This becomes the third letter.
• The fourth to last letter is W. This becomes the fourth letter.
• The fifth to last letter is E. This becomes the fifth letter.
• The sixth to last letter is H. This becomes the sixth letter.
• The first letter is C. This becomes the last letter.

Putting these letters together in the reversed order, we get: G N I W E H C.

Comparing with Options

We have found that 'CHEWING' should be coded as 'GNIWEHC'. Now let's look at the given options:

• Option 1: ECHNIGW
• Option 2: HGWENIC
• Option 3: GNIEHWC
• Option 4: GNIWEHC

Our calculated coded word 'GNIWEHC' exactly matches Option 4.

Conclusion

Based on the pattern observed in the example 'PERHAPS' being coded as 'SPAHREP' (simple reversal of letters), applying the same pattern to 'CHEWING' results in 'GNIWEHC'.

Revision Table: Coding Language Review

Reviewing the key elements of this type of coding problem:

• Identify the relationship between the original word and the coded word in the example provided.
• Look for patterns like reversal, shifting of letters, substitution, or rearrangement.
• Once the pattern is confirmed, apply it consistently to the new word.
• Compare your result with the given options to find the correct answer.

Additional Information: Types of Coding Patterns

Coding-decoding problems in reasoning tests often use various patterns. Some common types include:

• Letter Reversal: As seen in this problem, the order of letters is reversed.
• Letter Shifting: Each letter is shifted a certain number of positions forward or backward in the alphabet (e.g., A becomes B, B becomes C, or A becomes Z, B becomes Y).
• Letter Substitution: Each letter is replaced by a specific letter (e.g., A is always replaced by X, B by Y).
• Position Interchange: Letters at specific positions are swapped (e.g., 1st and 2nd letters swapped, 3rd and 4th swapped).
• Mixed Patterns: A combination of the above patterns might be used.

Solving these problems requires careful observation and logical deduction to identify the specific rule being followed.
