Answer
Correct Answer: 27685
Explanation
Introduction / Context:We again have a direct substitution mapping letters to digits, with two examples sufficient to determine all letters in the target word.
Given Data / Assumptions:
- From GRAPE: G→2, R→7, A→3, P→5, E→4.
- From FOUR: F→1, O→6, U→8, R→7 (confirms).
- Target word: GROUP = G R O U P.
Concept / Approach:Substitute each letter using the fixed mapping dictionary.
Step-by-Step Solution:G→2, R→7, O→6, U→8, P→5 → 27685.
Verification / Alternative check:All letters used in GROUP appear in the examples; there is no ambiguity.
Why Other Options Are Wrong:
- Each alternative mis-maps at least one letter (e.g., swaps last two digits or changes O/U values).
Common Pitfalls:Reordering digits or forgetting previously established mappings.
Final Answer:27685
