Decode the symbol string to digits using the given number→symbol coding. Coding: 1→!, 2→@, 3→#, 4→$, 5→%, 6→^, 7→&, 8→*, 9→+ Given symbols: ^ + # % @

Difficulty: Easy

Correct Answer: 69352

Explanation:


Introduction / Context:
We invert a simple number→symbol substitution and read off the digits.


Given Data / Assumptions:

  • 1→!, 2→@, 3→#, 4→$, 5→%, 6→^, 7→&, 8→*, 9→+.
  • Symbols: ^ + # % @.


Concept / Approach:
Translate each symbol to its digit by the inverse mapping.


Step-by-Step Solution:

^ → 6+ → 9# → 3% → 5@ → 2Number: 69352


Verification / Alternative check:
Re-encode 69352 to regain ^ + # % @.


Why Other Options Are Wrong:

  • They swap at least one adjacent pair (e.g., 35 vs 53) or misread + as 7 or 8.


Common Pitfalls:
Confusing + (9) with & (7) due to visual density; always check the legend.


Final Answer:
69352
