Answer
Correct Answer: 57K5
Explanation
Introduction / Context:We are given two coded words that reveal a one-to-one mapping from letters to symbols or digits. The task is to reuse the same mapping to encode a new word.
Given Data / Assumptions:
- BEAM → 5 % * K
- COME → $ 7 K %
- Hence mappings: B→5, E→%, A→*, M→K, C→$, O→7.
Concept / Approach:Apply the mapping letter by letter to BOMB. Remove spacing to keep a clean, unambiguous code string.
Step-by-Step Solution:B → 5O → 7M → KB → 5Therefore, BOMB → 57K5.
Verification / Alternative check:Cross-check by reversing: 57K5 decodes back to BOMB using the same dictionary.
Why Other Options Are Wrong:
- 5%K5: Uses E’s symbol % instead of O’s 7.
- $7K$: Mixes C and O incorrectly and uses C twice.
- 5$%5: Combines B, C, and E symbols; does not match O and M positions.
Common Pitfalls:Confusing O with 0, retaining spaces from examples, or misreading symbol assignments.
Final Answer:57K5
