The correct answer is

1215184

Understanding the Coding Pattern in the Language

The problem asks us to decode the word "LORD" based on how "DEAF" and "KILL" are encoded in a specific code language. To solve this, we need to analyze the relationship between the letters of the given words and the numbers they are encoded into.

Let's look at the first example:

  • Word: DEAF
  • Code: 4516

Now, let's consider the position of each letter in the English alphabet:

  • D is the 4th letter.
  • E is the 5th letter.
  • A is the 1st letter.
  • F is the 6th letter.

If we put these position numbers together, we get 4, 5, 1, 6. Concatenating these numbers gives us "4516", which matches the given code for "DEAF".

Verifying the Pattern with the Second Example

Let's check if this pattern holds true for the second example:

  • Word: KILL
  • Code: 1191212

Let's find the position of each letter in the English alphabet for "KILL":

  • K is the 11th letter.
  • I is the 9th letter.
  • L is the 12th letter.
  • L is the 12th letter.

Putting these position numbers together gives us 11, 9, 12, 12. Concatenating these numbers gives us "1191212", which perfectly matches the given code for "KILL".

The pattern is confirmed: Each letter in the word is replaced by its corresponding position number in the English alphabet, and these numbers are joined together to form the code.

Encoding the Word "LORD" using the Alphabet Position Code

Now we will apply the same pattern to the word "LORD" to find its code.

We need to find the position of each letter in "LORD" in the English alphabet:

  • L is the 12th letter.
  • O is the 15th letter.
  • R is the 18th letter.
  • D is the 4th letter.

Let's list the letters and their positions:

Letter Alphabet Position
L 12
O 15
R 18
D 4

Now, we concatenate these position numbers: 12, 15, 18, 4.

Joining these numbers gives us the code: 1215184.

Conclusion: The Code for LORD

Based on the coding pattern where each letter is replaced by its alphabet position, the word "LORD" is encoded as "1215184".

Revision Table: Letter Positions for LORD

Letter Alphabet Position Encoded Value
L 12th 12
O 15th 15
R 18th 18
D 4th 4

Concatenating 12, 15, 18, and 4 gives 1215184.

Additional Information on Coding Patterns

Code language questions often use various patterns. Besides using the direct alphabet position (A=1, B=2, ... Z=26), other common patterns include:

  • Reverse Alphabet Position: Assigning positions in reverse order (A=26, B=25, ... Z=1).
  • Shifting: Shifting letters by a fixed number of positions (like Caesar cipher).
  • Opposite Letters: Replacing a letter with the letter directly opposite to it in the alphabet (A <-> Z, B <-> Y, etc.).
  • Vowel/Consonant Based Coding: Using different rules for vowels and consonants.
  • Skipping Letters: Assigning numbers based on skipping letters in a sequence.

Practicing different types of coding patterns helps in quickly identifying the rule in such problems.
