Correct Answer: 709832
Explanation
Introduction / Context:This is a direct substitution coding problem. Each letter maps to a specific digit. The task is to apply the table consistently from left to right.
Given Data / Assumptions:
- Mapping: V→7, G→0, I→9, X→8, R→3, M→2.
- Target string: VGIXRM (exact order must be preserved).
Concept / Approach:For a one-to-one table, simply replace each letter with its corresponding digit, taking care not to transpose adjacent positions.
Step-by-Step Solution:
V → 7G → 0I → 9X → 8R → 3M → 2Result: 709832Verification / Alternative check:Re-read the mapping in reverse: 7→V, 0→G, 9→I, 8→X, 3→R, 2→M to recover the original string.
Why Other Options Are Wrong:
- 709823, 709835, 708635: Each has at least one digit that does not match the provided letter mapping (e.g., the positions for X, R, or M become incorrect).
Common Pitfalls:Swapping the last two digits (R and M) or mistaking X for 0 instead of 8.
Final Answer:709832
