In code language, ‘ROLLER’ is written as ‘TQNJCP’, then how will ‘DOCILE’ be written as in that language?
FQEGJC
Understanding Code Language and Encoding
This question asks us to decipher a code language pattern and apply it to a new word. We are given an example of how the word 'ROLLER' is encoded into 'TQNJCP'. Our task is to use this pattern to encode the word 'DOCILE'.
Analyzing the Code Pattern for 'ROLLER' to 'TQNJCP'
Let's look at each letter in 'ROLLER' and its corresponding letter in 'TQNJCP' to find the rule. We can consider the alphabetical position of each letter.
The letters in 'ROLLER' are R, O, L, L, E, R.
The letters in 'TQNJCP' are T, Q, N, J, C, P.
| Original Letter | Position | Coded Letter | Position | Change |
|---|---|---|---|---|
| R | 18 | T | 20 | $+2$ |
| O | 15 | Q | 17 | $+2$ |
| L | 12 | N | 14 | $+2$ |
| L | 12 | J | 10 | $-2$ |
| E | 5 | C | 3 | $-2$ |
| R | 18 | P | 16 | $-2$ |
From the table, we can observe the pattern:
- The first three letters (R, O, L) are shifted forward by 2 positions in the alphabet ($+2$).
- The next three letters (L, E, R) are shifted backward by 2 positions in the alphabet ($-2$).
Applying the Pattern to 'DOCILE'
Now, we apply the same rule to the word 'DOCILE'. The letters in 'DOCILE' are D, O, C, I, L, E.
- First three letters: D, O, C. Apply $+2$.
- Last three letters: I, L, E. Apply $-2$.
| Original Letter | Position | Operation | New Position | Coded Letter |
|---|---|---|---|---|
| D | 4 | $+2$ | $4+2=6$ | F |
| O | 15 | $+2$ | $15+2=17$ | Q |
| C | 3 | $+2$ | $3+2=5$ | E |
| I | 9 | $-2$ | $9-2=7$ | G |
| L | 12 | $-2$ | $12-2=10$ | J |
| E | 5 | $-2$ | $5-2=3$ | C |
Applying the rule, 'DOCILE' is encoded as 'FQEGJC'.
Comparing with Options
Let's compare our result 'FQEGJC' with the given options:
- FPEHID
- FPFGJC
- FQEGJC
- EPFGKD
Our encoded word 'FQEGJC' matches option 3.
Revision Table: Code Language Patterns
Understanding different types of code language patterns is important for solving such questions. Here are a few common types:
| Pattern Type | Description | Example |
|---|---|---|
| Letter Shifting | Letters are shifted by a fixed number of positions forward or backward in the alphabet. The shift can be constant or vary based on position. | A $\to$ C ($+2$), B $\to$ D ($+2$) |
| Reverse Ordering | The letters of the word are written in reverse order. | CAT $\to$ TAC |
| Mixed Shifting | A combination of forward and backward shifting, or varying shift amounts for different letters or groups of letters, as seen in this problem. | First half +N, Second half -M |
| Letter Substitution | Each letter is replaced by another specific letter or symbol, not necessarily based on alphabetical position. | A $\to$ Z, B $\to$ Y (Reverse Alphabet) |
Additional Information: Logical Reasoning in Encoding Questions
Code language questions are a common type of logical reasoning problem. They test your ability to identify patterns and rules based on the relationship between the original and encoded forms of words or numbers.
Key steps to solve encoding problems:
- Carefully examine the given example (original word and encoded word).
- Analyze the transformation for each letter or element. Look for shifts, substitutions, reversals, or combinations.
- Note the position of the letter/element, as the rule might apply differently to different positions (e.g., first half vs. second half).
- Once the pattern is identified, apply it consistently to the word or number you need to encode or decode.
- Check your result against the given options.
Practice with different examples helps in quickly identifying various encoding patterns.
