Understanding the Coding-Decoding Pattern

This question asks us to identify a coding pattern used to transform the word 'COMPUTER' into 'OCREPMTU' and then apply the same pattern to the word 'DAUGHTER'. These types of problems test your ability to recognize logical rules applied to letters or numbers.

Analyzing the Transformation of COMPUTER

Let's look at the original word COMPUTER and its coded form OCREPMTU:

• Original Word: C O M P U T E R
• Coded Word:   O C R E P M T U

Both words have 8 letters. Let's assign positions to the letters in the original word and see where they move in the coded word.

By examining which letter from the original word appears at each position in the coded word, we can find the pattern. The letter that was originally at position 2 is now at position 1 in the code. The letter at original position 1 is now at position 2, and so on.

The order of letters in the coded word corresponds to the letters from these original positions:

New Position 1 → Original Position 2 (O)

New Position 2 → Original Position 1 (C)

New Position 3 → Original Position 8 (R)

New Position 4 → Original Position 7 (E)

New Position 5 → Original Position 4 (P)

New Position 6 → Original Position 3 (M)

New Position 7 → Original Position 6 (T)

New Position 8 → Original Position 5 (U)

So, the coded word is formed by taking the letters from the original word in the sequence of original positions: 2, 1, 8, 7, 4, 3, 6, 5.

Applying the Pattern to DAUGHTER

Now, let's apply this same sequence of original positions (2, 1, 8, 7, 4, 3, 6, 5) to the word DAUGHTER.

• Original Word: D A U G H T E R
• Original Position: 1 2 3 4 5 6 7 8

Using the sequence 2, 1, 8, 7, 4, 3, 6, 5:

Position 2 letter: A

Position 1 letter: D

Position 8 letter: R

Position 7 letter: E

Position 4 letter: G

Position 3 letter: U

Position 6 letter: T

Position 5 letter: H

Combining these letters in order gives us the coded word: A D R E G U T H.

Checking the Options

Let's compare our result ADREGUTH with the given options:

1. ADREGUTH - Matches our coded word.
2. READTHGU - Does not match.
3. ADTHREGU - Does not match.
4. DERUGTH - Does not match and has fewer letters.

The coded word for DAUGHTER is ADREGUTH.

Additional Information: Solving Coding Questions

To solve coding-decoding questions effectively, consider these steps:

• Look at the length of the words. Is it the same?
• Compare the letters in the original and coded words. Are they the same letters, just rearranged? Or are they different letters?
• If letters are rearranged, try to find the rule for position changes. Look at pairs of letters, halves of the word, or specific positions (first, last, middle).
• If letters are different, look for patterns like shifting in the alphabet (e.g., A becomes B, C becomes D), substitution based on a key, or patterns involving vowels/consonants.
• Once you find a potential rule, test it rigorously on the given example (COMPUTER to OCREPMTU). Make sure it works for every letter.
• Apply the confirmed rule to the new word (DAUGHTER).
• Check your answer against the options provided.

Practice with different types of coding-decoding puzzles helps you recognize patterns faster.
