Code Decoding Logic for 'T'

The problem provides two coded words and asks for the code of a specific letter.

• 'SEMI' is coded as '3615'.
• 'TIME' is coded as '1523'.

Identifying Common Elements

We compare the letters and the digits in the codes for both words to find a pattern.

• Common Letters: 'I', 'M', 'E' appear in both 'SEMI' and 'TIME'.
• Common Digits: '1', '5', '3' appear in both codes '3615' and '1523'.

Deducing Letter-to-Digit Mapping

By comparing the common letters with the common digits, we can establish potential mappings. Since each letter likely corresponds to a unique digit:

• 'I' corresponds to '5'.
• 'M' corresponds to '1'.
• 'E' corresponds to '3'.

Determining the Code for 'T'

Now, we use the established mappings to find the codes for the remaining letters:

• In 'SEMI' (coded as 3615): With E=3, M=1, I=5, the remaining letter 'S' must correspond to the remaining digit '6'. So, S = 6.
• In 'TIME' (coded as 1523): With I=5, M=1, E=3, the remaining letter 'T' must correspond to the remaining digit '2'. So, T = 2.

The mapping derived is: S=6, E=3, M=1, I=5, T=2. The code for the letter 'T' is 2.
