Understanding the Coding Language Pattern

The question asks us to decipher a specific code language where the word BEAT is coded as YVZG. We then need to apply the same coding rule to find the code for the word MILD.

Let's analyze the relationship between the letters in BEAT and YVZG.

• B corresponds to Y
• E corresponds to V
• A corresponds to Z
• T corresponds to G

We can look at the positions of these letters in the English alphabet (A=1, B=2, ..., Z=26).

Let's examine the sum of the positions of the original letter and its coded letter:

• B (2) + Y (25) = 27
• E (5) + V (22) = 27
• A (1) + Z (26) = 27
• T (20) + G (7) = 27

The pattern is clear: Each letter is replaced by the letter that is at the corresponding position from the opposite end of the alphabet. For example, A is the 1st letter from the beginning, and Z is the 1st letter from the end. B is the 2nd from the beginning, and Y is the 2nd from the end. This is also known as the 'opposite letter' code.

Applying the Code to MILD

Now, we apply this same pattern to the word MILD.

• M: M is the 13th letter. The letter at position \(27 - 13 = 14\) from the beginning is N. So, M codes to N.
• I: I is the 9th letter. The letter at position \(27 - 9 = 18\) from the beginning is R. So, I codes to R.
• L: L is the 12th letter. The letter at position \(27 - 12 = 15\) from the beginning is O. So, L codes to O.
• D: D is the 4th letter. The letter at position \(27 - 4 = 23\) from the beginning is W. So, D codes to W.

Combining the coded letters for M, I, L, and D, we get NROW.

Therefore, the code of MILD is NROW.

Checking the Options

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

1. ONRW
2. NOWR
3. ONWR
4. NROW

Our calculated code NROW matches option 4.

Additional Information: Opposite Letter Coding

The coding method used here is a type of substitution cipher known as an 'opposite letter' code or sometimes called an 'Atbash' cipher variant (though Atbash specifically applies to Hebrew). In the standard English alphabet version, each letter is mapped to the letter that is equally distant from the opposite end. This is a simple and common type of letter coding used in reasoning and coding-decoding questions.

Here's a simple mapping of opposite letters:

Recognizing this simple pattern is key to solving such coding language problems efficiently.
