Answer 1

The Correct Option is A

Step 1: Understanding the Concept:
Replace operators according to the given code.

Step 2: Detailed Explanation:
Given: ‘+’ → ‘×’, ‘-’ → ‘÷’, ‘×’ → ‘-’, ‘÷’ → ‘+’.
Expression: \(6 + 64 - 8 ÷ 45 × 8\)
Becomes: \(6 × 64 ÷ 8 + 45 - 8\)
Applying BODMAS:
\(6 × (64 ÷ 8) + 45 - 8 = 6 × 8 + 45 - 8 = 48 + 45 - 8 = 85\).

Step 3: Final Answer:
The value is 85.
