In a certain code language, ‘ABSTRACT’ is written as ‘IIYYVDEU’. How will ‘INSTINCT’ be written in that language?
QUYYMQEU
Decoding the Code Language Pattern
The question asks us to decipher a specific code language where the word 'ABSTRACT' is encoded as 'IIYYVDEU'. We then need to apply the same coding logic to the word 'INSTINCT' to find its coded form.
Let's analyze the transformation from 'ABSTRACT' to 'IIYYVDEU'. We can look at the alphabetical position of each letter in the original word and its corresponding letter in the coded word.
| Original Letter | Position | Coded Letter | Position | Shift |
|---|---|---|---|---|
| A | 1 | I | 9 | $9 - 1 = +8$ |
| B | 2 | I | 9 | $9 - 2 = +7$ |
| S | 19 | Y | 25 | $25 - 19 = +6$ |
| T | 20 | Y | 25 | $25 - 20 = +5$ |
| R | 18 | V | 22 | $22 - 18 = +4$ |
| A | 1 | D | 4 | $4 - 1 = +3$ |
| C | 3 | E | 5 | $5 - 3 = +2$ |
| T | 20 | U | 21 | $21 - 20 = +1$ |
From the table above, we can see a clear pattern in the shift applied to each letter's position:
- The first letter (A) is shifted by +8 positions.
- The second letter (B) is shifted by +7 positions.
- The third letter (S) is shifted by +6 positions.
- ...and so on, until the last letter (T), which is shifted by +1 position.
The pattern is a decreasing shift starting from +8 for the first letter and ending with +1 for the last letter.
Applying the Pattern to 'INSTINCT'
Now, we apply this discovered pattern to the word 'INSTINCT'. 'INSTINCT' also has 8 letters, so we will apply shifts of +8, +7, +6, +5, +4, +3, +2, +1 respectively to each letter.
| Original Letter | Position | Shift | New Position | Coded Letter |
|---|---|---|---|---|
| I | 9 | +8 | $9 + 8 = 17$ | Q |
| N | 14 | +7 | $14 + 7 = 21$ | U |
| S | 19 | +6 | $19 + 6 = 25$ | Y |
| T | 20 | +5 | $20 + 5 = 25$ | Y |
| I | 9 | +4 | $9 + 4 = 13$ | M |
| N | 14 | +3 | $14 + 3 = 17$ | Q |
| C | 3 | +2 | $3 + 2 = 5$ | E |
| T | 20 | +1 | $20 + 1 = 21$ | U |
Following the pattern, the word 'INSTINCT' is coded as 'QUYYMQEU'.
Conclusion
By analyzing the coding of 'ABSTRACT' as 'IIYYVDEU', we identified a pattern of decreasing positional shifts (+8, +7, +6, +5, +4, +3, +2, +1). Applying this pattern to 'INSTINCT', we found the coded word to be 'QUYYMQEU'.
Revision Table: Key Coding-Decoding Concepts
| Concept | Description | Example |
|---|---|---|
| Letter Shifting | Each letter is shifted forward or backward by a fixed number or a varying number. | A > C (+2), B > D (+2) |
| Positional Changes | Letters in the word might be rearranged or their positions within the word affect the code. | Reverse order, alternating positions |
| Opposite Letters | Coding based on letters at opposite ends of the alphabet (A-Z, B-Y, etc.). | A > Z, B > Y |
| Direct Letter Coding | Each letter in the original word is directly substituted by a specific letter/symbol in the code, often context-dependent. | If 'CAT' is coded as 'DOG' (letter 'C' is 'D', 'A' is 'O', 'T' is 'G') - though this is very rare. More often, it's consistent substitution. |
Additional Information: Tips for Solving Coding Questions
- Write down the original word and the coded word, aligning the letters.
- Write down the alphabetical position of each letter.
- Calculate the difference in positions or look for patterns in the shifts.
- Check for patterns like reverse order, skips, blocks of letters, etc.
- If the pattern isn't immediately obvious, consider other types of coding like opposite letters.
- Apply the identified pattern consistently to the word you need to encode or decode.
- Verify your result by comparing it with the given options.
