Understanding the Coding Decoding Pattern

This coding decoding question requires us to identify the pattern used to convert words into numbers. We are given two examples: 'SAW' coded as '427' and 'REEF' coded as '3556'. Our goal is to apply the same logic to find the code for 'WAFERS'.

Analyzing the Given Codes

Let's look at the letters in the given words and their corresponding positions in the codes:

By comparing the letters and their corresponding digits, we can deduce a simple letter-to-digit substitution. Let's consolidate the letter codes we found:

• S = 4
• A = 2
• W = 7
• R = 3
• E = 5
• F = 6

This pattern seems consistent across both examples. Each letter is assigned a unique digit.

Coding the Word 'WAFERS'

Now, we will apply the same letter-to-digit mapping to the word 'WAFERS'. We need to find the code for each letter in 'WAFERS' using the mapping we deduced:

• W: From 'SAW' coded as '427', W is the third letter and corresponds to the third digit, 7. So, W = 7.
• A: From 'SAW' coded as '427', A is the second letter and corresponds to the second digit, 2. So, A = 2.
• F: From 'REEF' coded as '3556', F is the fourth letter and corresponds to the fourth digit, 6. So, F = 6.
• E: From 'REEF' coded as '3556', E is the second and third letter and corresponds to the second and third digit, 5. So, E = 5.
• R: From 'REEF' coded as '3556', R is the first letter and corresponds to the first digit, 3. So, R = 3.
• S: From 'SAW' coded as '427', S is the first letter and corresponds to the first digit, 4. So, S = 4.

Arranging the codes for each letter in 'WAFERS' in order:

• W → 7
• A → 2
• F → 6
• E → 5
• R → 3
• S → 4

Putting these digits together, the code for 'WAFERS' is 726534.

Final Code for WAFERS

Based on the letter-to-digit substitution pattern derived from 'SAW' (427) and 'REEF' (3556), the code for 'WAFERS' is 726534.

Additional Information: Letter Coding Concepts

Letter coding is a common type of question in logical reasoning. In such questions, letters of a word are replaced by other letters, numbers, or symbols based on a specific rule or pattern. To solve these questions, you need to:

• Observe the given examples carefully.
• Identify the pattern or rule used in the coding. This could be position shifting (like in the alphabet), direct substitution (as in this problem), or other logical transformations.
• Apply the identified pattern to the word for which the code is asked.
• Common patterns include:
  • Adding or subtracting a fixed number to the alphabetical position of each letter.
  • Reversing the order of letters.
  • Substituting letters with their opposite letters in the alphabetical series.
  • Using a unique digit or symbol for each letter, as seen in this question.
