In a certain code language, 'he came back' is written as 'ni ji pa', 'go back now' is written as 'pa ja ka' and 'stop it now' is written as 'ka my uk' . How will 'go' be written in the same code language?
Understanding Coding-Decoding Questions
Coding-decoding questions require you to identify the pattern or rule used to assign codes to words or phrases. In this specific question, we are given three sentences and their corresponding codes. Our goal is to find the code for the word 'go' by comparing the given pairs.
Let's list the given information:
- 'he came back' is coded as 'ni ji pa'
- 'go back now' is coded as 'pa ja ka'
- 'stop it now' is coded as 'ka my uk'
We need to find the code for the word 'go'. To do this, we should look for common words in the sentences and identify their common codes.
Step-by-Step Decoding Process
We will compare the sentences pair by pair to find common words and their corresponding codes.
Comparison of Sentence 1 and Sentence 2
- Sentence 1: 'he came back' = 'ni ji pa'
- Sentence 2: 'go back now' = 'pa ja ka'
The common word in Sentence 1 and Sentence 2 is 'back'.
The common code in the codes for Sentence 1 ('ni ji pa') and Sentence 2 ('pa ja ka') is 'pa'.
Therefore, the code for 'back' is 'pa'.
We can represent this deduction:
| Word | Code |
|---|---|
| back | pa |
Comparison of Sentence 2 and Sentence 3
- Sentence 2: 'go back now' = 'pa ja ka'
- Sentence 3: 'stop it now' = 'ka my uk'
The common word in Sentence 2 and Sentence 3 is 'now'.
The common code in the codes for Sentence 2 ('pa ja ka') and Sentence 3 ('ka my uk') is 'ka'.
Therefore, the code for 'now' is 'ka'.
We can represent this deduction:
| Word | Code |
|---|---|
| now | ka |
Finding the Code for 'go'
Now let's look back at Sentence 2:
'go back now' is coded as 'pa ja ka'
We have already determined that:
- 'back' is coded as 'pa'
- 'now' is coded as 'ka'
Substitute the known codes into the expression for Sentence 2:
'go' + 'back' + 'now' = 'pa' + 'ja' + 'ka'
'go' + 'pa' + 'ka' = 'pa' + 'ja' + 'ka'
By comparing both sides of the equation, we can see that the remaining word 'go' corresponds to the remaining code 'ja'.
Therefore, the code for 'go' is 'ja'.
Summary of Codes Found
| Word | Code |
|---|---|
| back | pa |
| now | ka |
| go | ja |
Based on our analysis, the code for 'go' in this language is 'ja'.
Revision Table: Coding Decoding Analysis
| Sentence | Code | Common Word(s) | Common Code(s) | Deduction |
|---|---|---|---|---|
| he came back | ni ji pa | back (with S2) | pa (with C2) | back = pa |
| go back now | pa ja ka | back (with S1), now (with S3) | pa (with C1), ka (with C3) | go = ja (by elimination) |
| stop it now | ka my uk | now (with S2) | ka (with C2) | now = ka |
Additional Information: Types of Coding-Decoding
Coding-decoding problems are common in reasoning sections of competitive exams. They test your ability to decipher patterns and rules. Here are some common types:
- Letter Coding: Letters are replaced with other letters based on a specific pattern (e.g., shifting positions in the alphabet).
- Number/Symbol Coding: Words are assigned numerical or symbolic codes based on rules (e.g., position of letters, sum of values).
- Mixed Letter and Number Coding: A combination of letter and number codes.
- Sentence/Phrase Coding: As seen in this problem, entire phrases are coded, and you need to find the code for individual words by comparing different phrases.
- Word Substitution: Words are directly substituted with other words (e.g., 'blue' is called 'green').
Practicing different types helps you quickly identify the logic used in a particular problem.
