The correct answer is
20-1-8

Decoding Word Codes: HAT to TAH

This problem uses a simple substitution cipher where each letter is replaced by its numerical position in the alphabet.

Determining the Letter-Number Mapping

The provided code for 'HAT' is '8-1-20'. We can establish the mapping based on the alphabetical order:

  • The first letter, H, corresponds to the number $8$.
  • The second letter, A, corresponds to the number $1$.
  • The third letter, T, corresponds to the number $20$.

This confirms the mapping: H $\rightarrow$ $8$, A $\rightarrow$ $1$, T $\rightarrow$ $20$.

Applying the Code to TAH

Using the established mapping, we can now code the word 'TAH':

  • The first letter, T, corresponds to $20$.
  • The second letter, A, corresponds to $1$.
  • The third letter, H, corresponds to $8$.

Combining these numbers in order gives the code for 'TAH' as $20$-$1$-$8$.

Final Code

The word 'TAH' is coded as $20$-$1$-$8$.
