In a certain code language, ‘HAPPY’ is written as ‘JCRRA’ and ‘MAGIC’ is written as ‘OCIKE’. How will ‘LEVEL’ be written in that language?

Decoding the Pattern in Code Language Questions
This question asks us to find the code for the word 'LEVEL' based on the coding pattern used for 'HAPPY' and 'MAGIC'. These types of questions test our ability to identify logical rules applied to transform words.
Analyzing the Given Examples
We are given two examples of words and their coded forms:
- 'HAPPY' is coded as 'JCRRA'
- 'MAGIC' is coded as 'OCIKE'
We need to find the rule that transforms the letters in the original word to the letters in the coded word.
Finding the Coding Rule
Let's look at the alphabetical position of each letter in the original words and their corresponding letters in the coded words. We can think of A=1, B=2, C=3, and so on, up to Z=26.
| Original Word (HAPPY) | Position | Coded Word (JCRRA) | Position | Difference |
|---|---|---|---|---|
| H | 8 | J | 10 | $10 - 8 = +2$ |
| A | 1 | C | 3 | $3 - 1 = +2$ |
| P | 16 | R | 18 | $18 - 16 = +2$ |
| P | 16 | R | 18 | $18 - 16 = +2$ |
| Y | 25 | A | 1 | $(1 + 26) - 25 = +2$ (Wrapping around Z) |
| Original Word (MAGIC) | Position | Coded Word (OCIKE) | Position | Difference |
|---|---|---|---|---|
| M | 13 | O | 15 | $15 - 13 = +2$ |
| A | 1 | C | 3 | $3 - 1 = +2$ |
| G | 7 | I | 9 | $9 - 7 = +2$ |
| I | 9 | K | 11 | $11 - 9 = +2$ |
| C | 3 | E | 5 | $5 - 3 = +2$ |
From both examples, it is clear that each letter in the original word is shifted 2 places forward in the alphabet to get the corresponding letter in the coded word. When the shift goes beyond 'Z', we wrap around to 'A'.
Applying the Rule to 'LEVEL'
Now, let's apply this rule (adding +2 to the letter position) to each letter in the word 'LEVEL'.
- L: Position is 12. $12 + 2 = 14$. The 14th letter is N.
- E: Position is 5. $5 + 2 = 7$. The 7th letter is G.
- V: Position is 22. $22 + 2 = 24$. The 24th letter is X.
- E: Position is 5. $5 + 2 = 7$. The 7th letter is G.
- L: Position is 12. $12 + 2 = 14$. The 14th letter is N.
So, by applying the +2 shift to each letter of 'LEVEL', we get 'NGXGN'.
Conclusion
Based on the coding pattern identified from the examples 'HAPPY' -> 'JCRRA' and 'MAGIC' -> 'OCIKE', which involves shifting each letter 2 positions forward in the alphabet (with wrap-around from Z to A), the word 'LEVEL' is coded as 'NGXGN'.
Revision Table: Coding Decoding
Understanding the basics of letter positioning and common coding techniques is crucial for these questions.
| Concept | Description | Example Technique |
|---|---|---|
| Letter Positioning | Assigning numerical values to letters (A=1, B=2, ... Z=26) | Used to identify shifts in position |
| Shifting (Caesar Cipher) | Moving each letter a fixed number of positions forward or backward in the alphabet | '+2' shift as seen in this problem |
| Substitution | Replacing each letter with another letter or symbol based on a rule | Can be a simple shift or a mixed alphabet |
| Position Reversal | Coding letters based on their position from the end of the alphabet (A=26, B=25, ... Z=1) | Often combined with other shifts |
Additional Information: Logical Reasoning and Coding
Coding and decoding questions are a common part of logical reasoning sections in various exams. They assess your analytical skills and ability to spot patterns. Common patterns include:
- Adding or subtracting a fixed number from letter positions.
- Changing the position based on the position of the letter within the word (e.g., +1 for 1st letter, +2 for 2nd, etc.).
- Reversing the alphabetical position.
- Using opposite letters (A-Z, B-Y, etc.).
- Combining two or more simple rules.
Practicing with different types of coding patterns helps improve speed and accuracy in identifying the underlying logic.
