Understanding the Letter Coding Pattern

The problem provides a coding rule where the word IJKLMNO is coded as ACTVSRX. We need to figure out the specific pattern or substitution used in this coding and then apply it to find the code for the word KILL.

Analyzing the Given Code

Let's look at the mapping between the letters of IJKLMNO and ACTVSRX:

From this table, we can see that each letter in the word IJKLMNO is directly replaced by a specific letter in the coded word ACTVSRX. This is a simple direct substitution cipher where each letter has a unique coded equivalent within this specific rule.

Applying the Pattern to Code KILL

Now that we know the specific coding for each letter, we can apply this rule to the letters in the word KILL.

• The first letter in KILL is K. Looking at our table, K is coded as T.
• The second letter in KILL is I. Looking at our table, I is coded as A.
• The third letter in KILL is L. Looking at our table, L is coded as V.
• The fourth letter in KILL is L. Looking at our table, L is coded as V.

Determining the Coded Word for KILL

Putting the coded letters together in the order they appear in KILL, we get:

• K codes to T
• I codes to A
• L codes to V
• L codes to V

So, the word KILL is coded as TAVV.

Conclusion

Based on the direct substitution pattern derived from the coding of IJKLMNO as ACTVSRX, the word KILL is coded as TAVV.
