In a certain code language, ELEPHANTS is written as DMFOIBMUT. How will CROCODILE be written in the same code language?
BSPBPEHMF
Understanding Coding Language Patterns
This question involves decoding a pattern used in a specific code language. We are given a word, ELEPHANTS, and its coded form, DMFOIBMUT. Our task is to identify the rule applied to transform ELEPHANTS into DMFOIBMUT and then use that same rule to code the word CROCODILE.
Analyzing the ELEPHANTS Code
Let's look at the transformation of each letter from ELEPHANTS to DMFOIBMUT. We can determine the relationship between each letter and its coded counterpart by considering their positions in the English alphabet.
| Original Letter | Coded Letter | Alphabetical Shift |
|---|---|---|
| E | D | E → D (1 step back, -1) |
| L | M | L → M (1 step forward, +1) |
| E | F | E → F (1 step forward, +1) |
| P | O | P → O (1 step back, -1) |
| H | I | H → I (1 step forward, +1) |
| A | B | A → B (1 step forward, +1) |
| N | M | N → M (1 step back, -1) |
| T | U | T → U (1 step forward, +1) |
| S | T | S → T (1 step forward, +1) |
Identifying the Coding Rule
From the analysis above, we can see a clear pattern in the letter shifts:
- The 1st letter shifts -1.
- The 2nd letter shifts +1.
- The 3rd letter shifts +1.
- The 4th letter shifts -1.
- The 5th letter shifts +1.
- The 6th letter shifts +1.
- The 7th letter shifts -1.
- The 8th letter shifts +1.
- The 9th letter shifts +1.
The pattern of shifts is consistently -1, +1, +1, -1, +1, +1, -1, +1, +1 for the nine letters of the word ELEPHANTS.
Applying the Pattern to CROCODILE
Now we apply this same -1, +1, +1... pattern to the letters of the word CROCODILE. CROCODILE also has nine letters.
| Original Letter | Position | Shift Rule | Coded Letter |
|---|---|---|---|
| C | 1st | -1 | B |
| R | 2nd | +1 | S |
| O | 3rd | +1 | P |
| C | 4th | -1 | B |
| O | 5th | +1 | P |
| D | 6th | +1 | E |
| I | 7th | -1 | H |
| L | 8th | +1 | M |
| E | 9th | +1 | F |
Following the pattern, the coded letters for CROCODILE are B, S, P, B, P, E, H, M, F.
Combining these letters gives the coded word: BSPBPEHMF.
Matching with Options
Let's compare our derived coded word with the given options:
- Option 1: BQPBNEHKF
- Option 2: CSSDDPEJLF
- Option 3: BSPBPEHMF
- Option 4: DSPDPEJMF
Our coded word, BSPBPEHMF, matches Option 3.
Conclusion
Based on the identified coding language pattern where the shifts are -1, +1, +1, -1, +1, +1, -1, +1, +1 for successive letters, the word CROCODILE is coded as BSPBPEHMF.
Revision Table: Coding Decoding
| Concept | Description | Example Type |
|---|---|---|
| Letter Coding | Letters of a word are replaced by other letters based on a specific rule or pattern. | Alphabetical shifts (+/-), position-based shifts, skipping letters. |
| Pattern Identification | Analyzing the relationship between the original word and the coded word to find the rule. | Looking for consistent shifts, reversals, substitutions. |
| Applying the Rule | Using the identified pattern to code a new word or decode a coded word. | Applying the exact shift or rule to the new letters. |
Additional Information: Types of Coding Patterns
Coding-decoding questions often involve different types of patterns. Understanding these can help solve various problems:
- Alphabetical Shift: Each letter is shifted forward or backward by a fixed number of positions (e.g., +2, -3).
- Mixed Shift: The shift amount varies for different letters or positions, as seen in this problem (-1, +1, +1, etc.).
- Reverse Order: The letters of the word are written in reverse order, sometimes with an additional shift.
- Substitution: Specific letters are replaced by specific other letters or symbols.
- Position Based: The coding depends on the position of the letter in the word or its position in the alphabet.
- Word/Sentence Based: Entire words or sentences are coded based on inter-word relationships or fixed rules.
To solve coding-decoding problems effectively, it is crucial to practice identifying different types of patterns quickly and systematically.
