Understanding the Coding Language Pattern

The question asks us to decipher a specific code language based on two examples and then apply that code to a new word. We are given that OSTER is written as PTTDQ and TORSE is written as UPRRD. We need to find how STORE will be written in this code language.

Analyzing the Given Coded Words

Let's look at the transformation from the original words to their coded forms:

Example 1: OSTER → PTTDQ

• O → P
• S → T
• T → T
• E → D
• R → Q

Example 2: TORSE → UPRRD

• T → U
• O → P
• R → R
• S → R
• E → D

Identifying the Coding Pattern

Let's examine the shift in the position of each letter in the alphabet for both examples. We can represent a shift of one position forward as +1 and one position backward as -1. No shift is +0.

By comparing the shifts for both words, we can see a consistent pattern based on the position of the letter in the word:

• The 1st letter shifts by \(+1\).
• The 2nd letter shifts by \(+1\).
• The 3rd letter shifts by \(+0\).
• The 4th letter shifts by \(-1\).
• The 5th letter shifts by \(-1\).

This pattern (\(+1, +1, +0, -1, -1\)) seems to be the rule for this specific code language.

Applying the Pattern to STORE

Now, we apply the identified pattern (\(+1, +1, +0, -1, -1\)) to the word STORE.

Following the shifts, the word STORE is coded as TUOQD.

Conclusion

Based on the consistent coding pattern observed in the examples OSTER → PTTDQ and TORSE → UPRRD, applying the same pattern (\(+1, +1, +0, -1, -1\)) to the word STORE results in TUOQD.

Additional Information: Coding-Decoding Concepts

Coding-decoding questions are common in logical reasoning sections of competitive exams. They test your ability to identify patterns and rules used to encrypt words or messages. Some common types of patterns include:

• Letter Shifting: Letters are shifted a fixed number of positions forward or backward in the alphabet. The shift might be uniform for all letters, or vary based on position, letter type (vowel/consonant), etc.
• Position Change: Letters within the word are rearranged according to a specific rule.
• Substitution: Each letter or a group of letters is replaced by another letter, symbol, or number based on a predefined table or rule.
• Mixed Patterns: A combination of shifting, substitution, and position changes might be used.

Solving these questions requires careful observation, comparison of given examples, and systematic testing of potential patterns. Writing down the letters and their corresponding coded letters, and noting the shifts, is often helpful.
