Understanding the Code Language Pattern

This question asks us to decipher a coding language pattern and apply it to a new word. We are given that in this code language, the word BANKER is written as NABREK.

Our first step is to carefully analyze the transformation from BANKER to NABREK to understand the underlying rule or pattern used in this coding language.

Decoding the Encoding Pattern: BANKER to NABREK

Let's look at the original word and the encoded word and see how the letters have changed positions.

Original word: B A N K E R

Positions: 1 2 3 4 5 6

Encoded word: N A B R E K

Positions: 1 2 3 4 5 6

Let's see which original letter appears at which position in the encoded word. We can create a mapping:

• The letter at original position 3 (N) is now at encoded position 1.
• The letter at original position 2 (A) is now at encoded position 2.
• The letter at original position 1 (B) is now at encoded position 3.
• The letter at original position 6 (R) is now at encoded position 4.
• The letter at original position 5 (E) is now at encoded position 5.
• The letter at original position 4 (K) is now at encoded position 6.

This tells us that the letters from the original positions move to new positions according to the following mapping:

The rule is: Take the letter at original position 3 and place it first, then the letter at original position 2, then original position 1, then original position 6, then original position 5, and finally original position 4.

In short, the sequence of original positions (1, 2, 3, 4, 5, 6) is rearranged to become the sequence of new positions (3, 2, 1, 6, 5, 4) for the letters.

Applying the Coding Language Rule to STRING

Now we need to apply this same rule to the word STRING.

Original word: S T R I N G

Positions: 1 2 3 4 5 6

Let's apply the position mapping (3, 2, 1, 6, 5, 4) to the letters of STRING:

• The letter at original position 3 is R. This goes to the 1st position in the encoded word.
• The letter at original position 2 is T. This goes to the 2nd position in the encoded word.
• The letter at original position 1 is S. This goes to the 3rd position in the encoded word.
• The letter at original position 6 is G. This goes to the 4th position in the encoded word.
• The letter at original position 5 is N. This goes to the 5th position in the encoded word.
• The letter at original position 4 is I. This goes to the 6th position in the encoded word.

Putting these letters in their new positions, we get:

• Position 1: R (from original position 3)
• Position 2: T (from original position 2)
• Position 3: S (from original position 1)
• Position 4: G (from original position 6)
• Position 5: N (from original position 5)
• Position 6: I (from original position 4)

So, the encoded word for STRING is RTSGNI.

Comparing with the Options

Let's compare our result RTSGNI with the given options:

• Option 1: RSTGIN
• Option 2: RTSGNI
• Option 3: TSIRGN
• Option 4: RIGSNI

Our calculated encoded word, RTSGNI, matches Option 2.

Encoded Word for STRING

Following the same coding language pattern used for BANKER, the word STRING will be written as RTSGNI.

Let's summarize the coding language rule found:

Additional Information: Types of Letter Coding

Letter coding is a common type of question in reasoning and logic tests. Understanding different patterns can help solve these questions quickly. Some common patterns include:

• Alphabetical Shift: Each letter is shifted a fixed number of places forward or backward in the alphabet (e.g., A becomes B, B becomes C).
• Reverse Alphabetical Shift: Shifting backwards in the alphabet.
• Jumbling/Position Change: The letters in the word are rearranged based on a specific rule, like the pattern we saw in this question (e.g., reversing the word, swapping pairs of letters, or a complex positional change).
• Opposite Letters: Using the letters that are opposite in the alphabetical series (A is opposite Z, B is opposite Y, etc.).
• Mixed Patterns: Combinations of the above, or more complex rules involving consonant/vowel separation, skipping letters, etc.

Practicing different types helps in quickly identifying the pattern in coding language problems.
