Understanding Coding-Decoding Logic

This question involves a type of coding-decoding where each letter in a word is assigned a specific symbol or number. We need to find the pattern or mapping between the letters and their codes using the given examples.

We are given two coded words:

• 'BREAD' is coded as '5*#$9'
• 'BRANCH' is coded as '5*$!%8'

Let's compare the letters and their corresponding codes from both examples to find the unique code for each letter present.

From the comparison, we have established the following mapping for the letters present in the given words:

• B → 5
• R → *
• E → #
• A → $
• D → 9
• N → !
• C → %
• H → 8

Now we need to find the code for the word 'CAND'. We will use the mappings we just found for each letter in 'CAND':

• C → %
• A → $
• N → !
• D → 9

Combining the codes for each letter in order, the code for 'CAND' is %$!9.

Final Coding Solution for CAND

By applying the established letter-to-code mapping derived from 'BREAD' and 'BRANCH', the word 'CAND' is coded as follows:

C → %
A → $
N → !
D → 9

Therefore, 'CAND' is written as '%$!9'.

Additional Information on Letter Coding

Letter coding is a common topic in reasoning ability sections of competitive exams. These problems test your ability to identify patterns and apply a consistent rule or set of rules to transform one set of characters (like a word) into another (like a code).

Common types of letter coding include:

• Direct Letter Coding: Each letter is assigned a fixed code (symbol, number, or another letter) regardless of its position in the word. The current problem is an example of this type.
• Positional Letter Coding: The code for a letter depends on its position within the word, or there might be a shift in letter positions.
• Substitution Coding: Words are substituted with other words based on a logical connection or pattern.
• Mixed Coding: A combination of different coding rules might be used.

To solve direct letter coding problems, the best approach is to compare the given examples and create a mapping table like the one shown in the solution above. Look for common letters in the example words to confirm their codes.
