Compare the common letters in the given code words and directly map each letter to its corresponding digit.
Step 1: Analyze the given coded words
We are given two coded expressions: 'KNEW' is coded as '4682' and 'KINE' is coded as '6238'.
Step 2: Identify common letters and digits
The common letters in both words ('KNEW' and 'KINE') are K, N, and E. The common digits in their respective codes ('4682' and '6238') are 2, 6, and 8. The letter 'I' appears only in 'KINE' and its corresponding code '6238' contains the unique digit 3 which is not present in '4682'.
Step 3: Determine the code for 'I'
By direct letter-to-digit matching between 'KINE' and '6238', the letter 'I' corresponds to the digit 3.
A: 6 represents 'N' or 'K' in the given words. C: 2 represents 'W' or 'K'. D: 8 represents 'E'.
B is correct because the letter 'I' in 'KINE' corresponds to the unique digit 3 that is not present in the code for 'KNEW'.
