Understanding the Coding Language Pattern

The question asks us to decode a word based on a specific pattern observed in three examples. We need to analyze how 'RESTRICT' is transformed into 'CTRISTRE', 'STARTING' into 'NGTIARST', and 'MOUNTAIN' into 'INTAUNMO'. By identifying the rule, we can apply it to find the code for 'ENVELOPE'.

Analyzing the Examples

Let's look at the given transformations:

All the given words have 8 letters. Let's assign a position number to each letter in the original words (1 to 8 from left to right).

Consider 'RESTRICT':

• R (1)
• E (2)
• S (3)
• T (4)
• R (5)
• I (6)
• C (7)
• T (8)

The coded word is 'CTRISTRE':

• C (from RESTRICT position 7)
• T (from RESTRICT position 8)
• R (from RESTRICT position 5)
• I (from RESTRICT position 6)
• S (from RESTRICT position 3)
• T (from RESTRICT position 4)
• R (from RESTRICT position 1)
• E (from RESTRICT position 2)

So, the pattern of letter positions from the original word to the coded word is: 7, 8, 5, 6, 3, 4, 1, 2.

Verifying the Pattern with Other Examples

Let's check this pattern with 'STARTING':

• S (1), T (2), A (3), R (4), T (5), I (6), N (7), G (8)

Applying the pattern (7, 8, 5, 6, 3, 4, 1, 2):

• 7th letter: N
• 8th letter: G
• 5th letter: T
• 6th letter: I
• 3rd letter: A
• 4th letter: R
• 1st letter: S
• 2nd letter: T

This gives us 'NGTIARST', which matches the given coded word for 'STARTING'.

Now let's check with 'MOUNTAIN':

• M (1), O (2), U (3), N (4), T (5), A (6), I (7), N (8)

Applying the pattern (7, 8, 5, 6, 3, 4, 1, 2):

• 7th letter: I
• 8th letter: N
• 5th letter: T
• 6th letter: A
• 3rd letter: U
• 4th letter: N
• 1st letter: M
• 2nd letter: O

This gives us 'INTAUNMO', which matches the given coded word for 'MOUNTAIN'.

The pattern (7, 8, 5, 6, 3, 4, 1, 2) is consistent across all examples.

Applying the Pattern to 'ENVELOPE'

Now, we apply the same pattern to the word 'ENVELOPE'. First, number the letters:

• E (1)
• N (2)
• V (3)
• E (4)
• L (5)
• O (6)
• P (7)
• E (8)

Apply the pattern (7, 8, 5, 6, 3, 4, 1, 2) to these positions:

• 7th letter: P
• 8th letter: E
• 5th letter: L
• 6th letter: O
• 3rd letter: V
• 4th letter: E
• 1st letter: E
• 2nd letter: N

Combining these letters in the new order gives us the coded word: PELOVEEN.

Conclusion

Based on the identified pattern, the code for 'ENVELOPE' is 'PELOVEEN'. This matches one of the provided options.

Additional Information: Letter Coding and Reasoning

Letter coding is a common type of question in reasoning sections of competitive exams. These questions test your ability to identify patterns and rules in the way letters or words are coded. The patterns can be simple, like shifting letters by a certain number, or more complex, like rearranging letters based on their positions or other properties.

Key strategies for solving letter coding problems include:

• Write down the original and coded words clearly.
• Number the positions of the letters.
• Compare letter positions or letter values (A=1, B=2, etc.) to find a pattern.
• Look for shifts (e.g., A becomes C, B becomes D - a shift of +2) or rearrangements.
• Test the suspected pattern on all given examples.
• Apply the confirmed pattern to the target word.

This specific problem involves a rearrangement based on the original positions of the letters, splitting the word into two halves mentally helps visualize the swaps, but the strict numerical pattern is the most reliable method.
