Understanding the Coding Pattern
The question asks us to determine the code for the word 'ACTION' based on a given example: 'LETTER' is coded as 'ZLZYIO'. This type of question falls under logical reasoning and specifically tests coding and decoding skills. We need to identify the rule that transforms 'LETTER' into 'ZLZYIO' and then apply that same rule to 'ACTION'.
Analyzing the Example: LETTER to ZLZYIO
Let's analyze the relationship between the letters of the source word 'LETTER' and its coded form 'ZLZYIO'.
Source Word: L E T T E R
Coded Word: Z L Z Y I O
Initial analysis reveals that simple substitution or a consistent shift cipher doesn't apply, as the letter 'T' appears twice in 'LETTER' but maps to different letters ('Z' and 'Y') in the code. Similarly, 'E' maps to two different letters ('L' and 'I'). This indicates that the position of the letter within the word plays a crucial role in determining its code.
Let's try reversing the source word 'LETTER'.
Reversed Word: R E T T E L
Now, let's compare the reversed word 'RETTEL' with the coded word 'ZLZYIO' by looking at the shift in alphabet positions.
| Reversed Letter | Alphabet Position | Coded Letter | Alphabet Position | Shift Applied |
| R | $18$ | Z | $26$ | $+8$ |
| E | $5$ | L | $12$ | $+7$ |
| T | $20$ | Z | $26$ | $+6$ |
| T | $20$ | Y | $25$ | $+5$ |
| E | $5$ | I | $9$ | $+4$ |
| L | $12$ | O | $15$ | $+3$ |
From the table, we can see a pattern: each letter in the reversed word is shifted forward in the alphabet. The amount of shift decreases sequentially for each subsequent letter. The shifts are $+8, +7, +6, +5, +4, +3$.
Applying the Pattern to ACTION
Having identified the pattern (reverse the word and apply decreasing shifts: $+8, +7, +6, +5, +4, +3$), we can now apply it to the word 'ACTION'.
- Reverse the word 'ACTION':
The reverse of 'ACTION' is 'NOITCA'.
- Apply the decreasing shifts to the reversed word:
We will apply the shifts $+8, +7, +6, +5, +4, +3$ to the letters of 'NOITCA' based on their positions.
Reversed Letter Alphabet Position Shift Applied Resulting Position Coded Letter N $14$ $+8$ $14 + 8 = 22$ V O $15$ $+7$ $15 + 7 = 22$ V I $9$ $+6$ $9 + 6 = 15$ O T $20$ $+5$ $20 + 5 = 25$ Y C $3$ $+4$ $3 + 4 = 7$ G A $1$ $+3$ $1 + 3 = 4$ D
By combining the coded letters obtained in the correct order, we get the final code for 'ACTION'.
Conclusion
The resulting code for 'ACTION' following the identified pattern is 'VVOYGD'.
