Understanding Coding Decoding Questions

This question is a classic example of a coding-decoding puzzle. In these types of questions, words are assigned specific codes based on a hidden pattern or rule. Our goal is to identify the pattern and then use it to decode or code a given word or phrase.

Decoding the Sentences Step-by-Step

We are given three coded statements:

1. ‘bi n pi’ means ‘some good books’
2. ‘n bat like’ means ‘some real characters’
3. ‘pi like ti’ means ‘many good characters’

We need to find the code for "Many good books". Let's compare the statements to find common words and their codes.

Comparing Statement 1 and Statement 2

Statement 1: 'bi n pi' = 'some good books'
Statement 2: 'n bat like' = 'some real characters'

The common word in the meaning is "some".
The common code word is 'n'.
Therefore, the code for 'some' is 'n'.

Comparing Statement 1 and Statement 3

Statement 1: 'bi n pi' = 'some good books'
Statement 3: 'pi like ti' = 'many good characters'

The common word in the meaning is "good".
The common code word is 'pi'.
Therefore, the code for 'good' is 'pi'.

Comparing Statement 2 and Statement 3

Statement 2: 'n bat like' = 'some real characters'
Statement 3: 'pi like ti' = 'many good characters'

The common word in the meaning is "characters".
The common code word is 'like'.
Therefore, the code for 'characters' is 'like'.

Finding Remaining Codes

Now we can use the codes we've found to decode the remaining words:

• From Statement 1: 'bi n pi' = 'some good books'. We know 'n' is 'some' and 'pi' is 'good'. The only remaining word is 'books' and its code is 'bi'. So, the code for 'books' is 'bi'.
• From Statement 2: 'n bat like' = 'some real characters'. We know 'n' is 'some' and 'like' is 'characters'. The only remaining word is 'real' and its code is 'bat'. So, the code for 'real' is 'bat'.
• From Statement 3: 'pi like ti' = 'many good characters'. We know 'pi' is 'good' and 'like' is 'characters'. The only remaining word is 'many' and its code is 'ti'. So, the code for 'many' is 'ti'.

Summary of Decoded Words

We have successfully decoded the code for each word:

Coding the Target Phrase: "Many good books"

We need to find the code for "Many good books". Using our decoded list:

• The code for "Many" is 'ti'.
• The code for "good" is 'pi'.
• The code for "books" is 'bi'.

So, the code for "Many good books" is 'ti pi bi'. The order of the code words typically doesn't matter unless specified, as they represent the set of words in the phrase.

Checking the Options

Let's compare our result with the given options:

1. ti pi bi - This matches our decoded code for "Many good books".
2. pi bat bi - This would translate to "good real books".
3. n pi bi - This would translate to "some good books".
4. n bat bi - This would translate to "some real books".

Based on our decoding, the correct code for "Many good books" is 'ti pi bi'.

Additional Information: Types of Coding Decoding

Coding-decoding questions can appear in various forms in competitive exams. Some common types include:

• Letter Coding: Letters are replaced with other letters based on a sequence or pattern (e.g., shifting positions in the alphabet).
• Number Coding: Words are assigned numerical codes. This could be based on letter positions, number of letters, or other calculations.
• Symbol Coding: Words are coded using symbols.
• Mixed Coding: This is the type we just solved, where words are coded using other artificial words, and you need to find the code for each individual word by comparing sentences.
• Conditional Coding: Codes change based on certain conditions applied to the letters or numbers.

Solving these questions requires careful observation, comparison, and logical deduction to identify the underlying rule or pattern.
