Decoding the Pattern: SKYJACKING to AJYKSGNIKC

The question asks us to find the coded form of the word CHEAPJACKS based on the coding pattern used for SKYJACKING being coded as AJYKSGNIKC. To solve this, we first need to analyze the relationship between the original word SKYJACKING and its coded form AJYKSGNIKC.

Analyzing the Coding Pattern

Let's look at the word SKYJACKING and its coded version AJYKSGNIKC. Both words have 10 letters. Let's examine the letters and their positions:

• Original word: S K Y J A C K I N G
• Coded word: A J Y K S G N I K C

A direct letter-to-letter substitution or simple shift doesn't seem apparent. Let's try breaking the word into parts.

If we split the word SKYJACKING into two halves (each of 5 letters):

• First half: SKYJA
• Second half: CKING

Now let's look at the coded word AJYKSGNIKC and split it into two halves:

• First half: AJYKS
• Second half: GNIKC

Comparing the halves:

• Original first half: SKYJA
• Coded first half: AJYKS

Notice that AJYKS is the reverse of SKYJA. (S becomes A, K becomes J, Y becomes Y, J becomes K, A becomes S - reading from end to beginning of SKYJA).

• Original second half: CKING
• Coded second half: GNIKC

Notice that GNIKC is the reverse of CKING. (C becomes G, K becomes N, I becomes I, N becomes K, G becomes C - reading from end to beginning of CKING).

So, the coding pattern is:

1. Split the word into two equal halves.
2. Reverse each half individually.
3. Concatenate the reversed halves to get the coded word.

Applying the Pattern to CHEAPJACKS

Now let's apply this pattern to the word CHEAPJACKS.

The word CHEAPJACKS has 10 letters.

1. Split the word into two equal halves (5 letters each):
   • First half: CHEAP
   • Second half: JACKS
2. Reverse each half:
   • Reversed first half (CHEAP): PAEHC
   • Reversed second half (JACKS): SKCAJ
3. Concatenate the reversed halves: PAEHC + SKCAJ = PAEHCSKCAJ

The coded word for CHEAPJACKS should be PAEHCSKCAJ.

Comparing with Options

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

• Option 1: PAEHCSKCAJ - Matches our result.
• Option 2: PAAEHCSKCAJ - Does not match (extra 'A').
• Option 3: PAEHCCSKCAJ - Does not match (extra 'C').
• Option 4: PAEHCSKAJ - Does not match (missing 'C').

The coded form of CHEAPJACKS is PAEHCSKCAJ.

Conclusion

By analyzing the coding rule applied to SKYJACKING, we found that the word is split into two halves, and each half is reversed. Applying this same logic to CHEAPJACKS gives us the coded word PAEHCSKCAJ.

Revision Table: Understanding Coding Patterns

Additional Information: Types of Letter Coding

Letter coding is a common type of verbal reasoning question. Understanding different patterns can help solve these problems quickly. Some common types include:

• Letter Shifting: Each letter is shifted forward or backward by a certain number of positions in the alphabet.
• Reverse Order: The letters of the word are simply written in reverse order.
• Direct Letter Coding: A specific letter in the original word is replaced by a specific letter in the coded word, consistently throughout.
• Position-Based Coding: The positions of letters within the word or groups of letters are changed, as seen in this problem (reversing halves).
• Mixed Coding: A combination of different rules might be applied.

Practicing various types of coding and decoding questions helps in quickly identifying the underlying pattern.
