Understanding the Coding Language Pattern

This question asks us to decode a word based on a pattern observed in a given coded pair. The word 'JUPITER' is coded as 'JVOJSFR'. We need to find the pattern of transformation from 'JUPITER' to 'JVOJSFR' and then apply the same pattern to the word 'NEPTUNE'.

Analyzing the JUPITER - JVOJSFR Coding

Let's look at each letter of 'JUPITER' and its corresponding letter in 'JVOJSFR':

Observing the transformations, we can see a clear pattern:

• The 1st and 7th letters remain unchanged.
• The 2nd, 4th, and 6th letters are shifted one position forward (+1) in the alphabet.
• The 3rd and 5th letters are shifted one position backward (-1) in the alphabet.

The pattern of transformation for each letter position is: No change, +1, -1, +1, -1, +1, No change.

Applying the Pattern to NEPTUNE

Now, let's apply this same pattern to the word 'NEPTUNE', which also has 7 letters:

1. First letter (N): No change → N
2. Second letter (E): +1 position → The letter after E is F
3. Third letter (P): -1 position → The letter before P is O
4. Fourth letter (T): +1 position → The letter after T is U
5. Fifth letter (U): -1 position → The letter before U is T
6. Sixth letter (N): +1 position → The letter after N is O
7. Seventh letter (E): No change → E

Combining these letters, the coded word for 'NEPTUNE' is NFOUTOE.

Comparing with Options

Let's compare our derived code 'NFOUTOE' with the given options:

• Option 1: NDPSVME (Does not match)
• Option 2: NGOUTOE (Does not match the third letter)
• Option 3: NFOUTOE (Matches our derived code)
• Option 4: NFOSTOE (Does not match the fifth letter)

The coded word 'NFOUTOE' matches Option 3.

Additional Information: Coding and Decoding Concepts

Coding and decoding questions are common in reasoning sections of competitive exams. They test your ability to identify patterns and rules in letter or number sequences and apply them to new cases. Types of coding can include:

• Letter Coding: Letters are replaced with other letters based on a specific rule (like positional shift, skipping letters, reversing order, etc.). This question is an example of letter coding with positional shifts.
• Number Coding: Words are coded using numbers. This could be based on the alphabetical position of letters or other numerical relationships.
• Symbol Coding: Letters or words are coded using symbols.
• Mixed Coding: A combination of letters, numbers, and symbols might be used.
• Sentence Coding: Entire sentences or phrases are coded, often with multiple words being coded together, requiring you to figure out which code corresponds to which word.

To solve coding-decoding problems, always start by carefully analyzing the given example(s) to find the underlying rule or pattern. Once the pattern is clear, apply it consistently to the word or sequence you need to decode.
