Understanding the Letter Coding Pattern

This question asks us to decipher a specific code language based on given examples and then apply that code to a new word. The core of the problem is to identify the rule that transforms a word into a sequence of numbers.

We are given two examples:

• 'ATUL' is coded as '1-20-21-12'
• 'RAJU' is coded as '18-1-10-21'

Let's examine the relationship between the letters in the words and the corresponding numbers in their codes. A common pattern in such coding problems involves the alphabetical position of the letters.

Analyzing the Coding Examples

Let's look at the alphabetical position of each letter in the word 'ATUL':

Comparing these positions with the given code '1-20-21-12', we can see a direct match. The code for 'ATUL' is formed by listing the alphabetical positions of its letters in order, separated by hyphens.

Let's verify this pattern with the second example, 'RAJU':

The code given for 'RAJU' is '18-1-10-21'. Again, this matches the sequence of alphabetical positions of the letters in 'RAJU'.

Applying the Pattern to 'GITA'

Based on the analysis of 'ATUL' and 'RAJU', the rule for this code language is to represent each letter by its alphabetical position (A=1, B=2, ..., Z=26) and list these numbers in order, separated by hyphens.

Now, let's apply this rule to the word 'GITA'. We need to find the alphabetical position of each letter in 'GITA':

Following the pattern, the code for 'GITA' will be the sequence of these numbers separated by hyphens.

Therefore, 'GITA' will be coded as '7-9-20-1'.

Conclusion

The code for 'GITA' is '7-9-20-1'. We can check the given options to find the one that matches this code.

Revision Table: Letter Positions

Memorizing the alphabetical positions of letters is crucial for solving such coding problems quickly. Here's a quick reference for the letters in 'GITA':

Additional Information: Types of Coding Questions

Coding and decoding questions are common in reasoning sections of exams. They can involve various patterns, including:

• Letter <--> Number Coding: Like this problem, where letters are mapped to numbers based on their position, sum of positions, difference, etc.
• Letter <--> Letter Coding: Letters are substituted with other letters based on a shift in position (e.g., A codes to B, B codes to C) or other patterns.
• Word <--> Word Coding: Words are coded with other words based on logical relations, substitution, or mixing up letters.
• Symbol Coding: Letters or words are coded using symbols.

Practicing different types helps in quickly identifying the underlying pattern in new problems.
