Understanding Coding and Decoding in Reasoning

Coding and decoding questions are common in logical reasoning tests. They involve deciphering a pattern or rule used to transform one word or set of letters into another, and then applying that same rule to a new word.

Analyzing the Given Code: FOAMING to AOFMGNI

We are given that in a certain code language, the word 'FOAMING' is written as 'AOFMGNI'. Let's examine the transformation:

• Original Word: F O A M I N G
• Coded Word: A O F M G N I

Let's look at the positions of the letters:

• FOA (first 3 letters) becomes AOF (reversed order)
• M (4th letter) remains M
• ING (last 3 letters) becomes GNI (reversed order)

So, the rule is:

1. Reverse the first three letters.
2. Keep the fourth letter as it is.
3. Reverse the last three letters.

Applying the Coding Rule to BELIEVE

Now, we need to apply this same rule to the word 'BELIEVE'.

Let's break down 'BELIEVE':

• The word is 7 letters long.
• The first three letters are BEL.
• The fourth letter is I.
• The last three letters are EVE.

Following the rule:

1. Reverse the first three letters (BEL): This gives LEB.
2. Keep the fourth letter as it is (I): This remains I.
3. Reverse the last three letters (EVE): This gives EVE (reversing EVE still results in EVE).

Now, combine the transformed parts:

LEB + I + EVE = LEBIEVE

Matching the Coded Word with Options

The coded word for 'BELIEVE' according to the rule is 'LEBIEVE'. Let's compare this with the given options:

• Option 1: LEBEIEV
• Option 2: EBILVEE
• Option 3: LEBIEVE
• Option 4: MFCJFWF

The coded word 'LEBIEVE' exactly matches Option 3.

Conclusion

By analyzing the coding pattern used for 'FOAMING' to 'AOFMGNI', we determined the rule involves reversing the first three and last three letters while keeping the middle letter the same. Applying this rule to 'BELIEVE' yields 'LEBIEVE'.

Additional Information: Types of Coding Patterns

Coding and decoding questions can involve various patterns. Some common types include:

• Letter Shifting: Each letter is shifted a fixed number of positions forward or backward in the alphabet (e.g., A becomes C, B becomes D, etc.).
• Letter Reversal: The letters of a word or parts of a word are reversed.
• Replacement: Letters are replaced by other specific letters or symbols.
• Position Changes: Letters change their positions within the word based on a specific sequence or rule.
• Combination of Rules: A mix of the above rules applied simultaneously.
• Number/Symbol Coding: Words are coded using numbers or symbols based on letter position, value, or other rules.

Identifying the pattern is key to solving these problems. Look for changes in position, replacements, or mathematical operations applied to letter values.
