Solving Coding Decoding Questions

This question asks us to decode a word based on a pattern observed in given coded words. The core task is to identify the rule used to transform the original words into their coded forms and then apply that rule to the new word.

Identifying the Coding Pattern

Let's look at the first example provided:

Original Word: PENDANT

Coded Word: QFOEBOU

We can compare each letter of the original word with the corresponding letter in the coded word to find the relationship:

• P becomes Q
• E becomes F
• N becomes O
• D becomes E
• A becomes B
• N becomes O
• T becomes U

Observing this, we can see that each letter in the original word is shifted one position forward in the English alphabet to get the corresponding letter in the coded word. This is a simple letter shift cipher where the shift is +1.

Let's verify this pattern with the second example:

Original Word: LAWFUL

Coded Word: MBXGVM

Comparing letters:

• L becomes M (L + 1)
• A becomes B (A + 1)
• W becomes X (W + 1)
• F becomes G (F + 1)
• U becomes V (U + 1)
• L becomes M (L + 1)

The pattern holds true. The rule for this coding language is to replace each letter with the next letter in the English alphabet.

Applying the Pattern to IMPOSE

Now, we need to apply this identified pattern (each letter +1) to the word "IMPOSE" to find its coded form.

Let's transform each letter of "IMPOSE":

• I → The letter after I is J.
• M → The letter after M is N.
• P → The letter after P is Q.
• O → The letter after O is P.
• S → The letter after S is T.
• E → The letter after E is F.

Putting these coded letters together, the word "IMPOSE" is coded as "JNQPTF".

Comparing with Options

Let's check the options provided to find which one matches our result "JNQPTF".

Option 1: JNQPTF

Option 2: INPQSG

Option 3: KMPRSF

Option 4: IMQQSG

Our derived code "JNQPTF" exactly matches Option 1.

Step-by-Step Decoding Summary

Here is a summary of the steps taken:

1. Analyze the given examples (PENDANT → QFOEBOU, LAWFUL → MBXGVM).
2. Identify the pattern: Each letter is replaced by the next letter in the alphabet (+1 shift).
3. Apply the pattern to the word "IMPOSE".
4. I + 1 = J
5. M + 1 = N
6. P + 1 = Q
7. O + 1 = P
8. S + 1 = T
9. E + 1 = F
10. Combine the coded letters to get JNQPTF.
11. Match the result with the given options.

Therefore, "IMPOSE" is coded as "JNQPTF" in this language.

Additional Information: Common Coding Decoding Patterns

Coding and decoding questions often appear in logical reasoning sections of competitive exams. Recognizing common patterns helps solve these questions quickly.

• Alphabetical Shift: Each letter is shifted by a fixed number of positions forward or backward in the alphabet (like the +1 shift in this question).
• Reverse Alphabetical Order: Replacing a letter with its corresponding letter from the end of the alphabet (A → Z, B → Y, etc.).
• Skipping Letters: Replacing a letter by skipping a fixed number of letters in between.
• Position-Based Coding: The position of the letter in the word or the alphabet is used in the coding rule.
• Jumbling/Reordering: The letters within the word are rearranged according to a specific rule (e.g., reversing the word, swapping pairs of letters).
• Consonant/Vowel Changes: Different rules might apply to consonants and vowels.

Practicing various types of coding decoding problems helps in quickly identifying the underlying pattern.
