Letter-to-digit coding: FLATTER → 7238859 and MOTHER → 468159. Using the same mapping, how is MAMMOTH coded?

Introduction / Context:This is a direct substitution from letters to digits. Two examples provide enough mappings to encode a new word without ambiguity.

Given Data / Assumptions:

• From FLATTER: F→7, L→2, A→3, T→8, E→5, R→9.
• From MOTHER: M→4, O→6, T→8 (confirms), H→1, E→5 (confirms), R→9 (confirms).
• All instances of a letter map to the same digit.

Concept / Approach:Write MAMMOTH letter by letter and substitute using the compiled dictionary.

Step-by-Step Solution:M A M M O T H4 3 4 4 6 8 1 → 4344681

Verification / Alternative check:Check consistency against both given examples; no conflicts arise.

Why Other Options Are Wrong:

• They alter one or more digits, implying inconsistent letter mapping.

Common Pitfalls:Changing digits for repeated letters or mixing in digits not supported by the dictionary.

Final Answer:4344681
