Decoding the Code for 'K'

The question presents a coding challenge where words are represented by numbers. We need to find the specific code for the letter 'K' using the provided examples:

  • 'HIKE' is coded as '4627'.
  • 'SACK' is coded as '1365'.

The solution involves identifying a pattern or a consistent mapping between letters and digits.

Method: Identifying Common Elements

A common technique for solving such coding problems is to look for elements (letters or digits) that are shared between the given examples.

  1. List Letter-Digit Sets:
    • For 'HIKE' -> 4627: The set of letters is {H, I, K, E} and the set of digits is {4, 6, 2, 7}.
    • For 'SACK' -> 1365: The set of letters is {S, A, C, K} and the set of digits is {1, 3, 6, 5}.
  2. Identify Common Letter: By comparing the letters in both words, we find that 'K' is the only letter present in both 'HIKE' and 'SACK'.
  3. Identify Common Digit: By comparing the digits in both codes ('4627' and '1365'), we find that '6' is the only digit present in both codes.
  4. Establish the Code: In this type of puzzle, the common letter typically corresponds to the common digit. Therefore, the common letter 'K' corresponds to the common digit '6'.

Final Determination

Following the common element matching method, we conclude that the code for the letter 'K' is 6.
