Understanding the Coding Logic

This question is about a type of code where letters in a word are replaced by numbers. We are given two examples of this code and asked to figure out the number that represents the letter 'S'.

• Given Codes:
• The word 'MUST' is coded as '4268'.
• The word 'SALE' is coded as '3527'.

Finding the Code for the Letter 'S'

To solve this, we need to compare the letters in the words with the digits in their codes.

• Step 1: Compare the Words and Codes
• Word 1: MUST has letters {M, U, S, T} and the code uses digits {4, 2, 6, 8}.
• Word 2: SALE has letters {S, A, L, E} and the code uses digits {3, 5, 2, 7}.

We look for any similarities between the two sets of information.

• Step 2: Identify Common Elements
• Common Letter: The letter 'S' is present in both 'MUST' and 'SALE'. It's the only letter that appears in both words.
• Common Digit: By comparing the digits used in the codes (4268 and 3527), we find that the digit '2' is present in both codes. It's the only common digit.

• Step 3: Deduce the Code for 'S'
• Since 'S' is the only letter shared between the two words, and '2' is the only digit shared between the two codes, we can logically conclude that the letter 'S' must be represented by the digit '2'.

Solution Verification

The analysis shows a direct correspondence between the common letter 'S' and the common digit '2'. Therefore, the code for 'S' is 2.

Checking the options provided, the number 2 matches the code we found for 'S'.
