109
First rewrite the given equation by replacing each mathematical operator according to the rule, then apply the BODMAS rule (Division, Multiplication, Addition, Subtraction).
First rewrite the given equation by replacing each mathematical operator according to the rule, then apply the BODMAS rule (Division, Multiplication, Addition, Subtraction).
Step 1: Write down the given operator replacements
Given rules are: '+' means '-', '-' means 'x', 'x' means '/', '/' means '+'.
Step 2: Substitute operators in the equation
The given expression is: 22 - 5 / 3 + 12 x 3. Replacing the operators gives: 22 x 5 + 3 - 12 / 3.
Step 3: Apply BODMAS rule
First Division: 12 / 3 = 4. Next Multiplication: 22 x 5 = 110. Then Addition: 110 + 3 = 113. Finally Subtraction: 113 - 4 = 109.
A: 111 is incorrect due to incorrect arithmetic during addition/subtraction. C: 112 is incorrect and does not follow proper BODMAS sequence. D: 110 is incorrect as it misses the final subtraction step.
109 is correct because substituting the symbols and applying the BODMAS rule yields (22 x 5) + 3 - (12 / 3) = 110 + 3 - 4 = 109.
Always carefully replace each operator first before evaluating; rewriting the expression prevents common sign-confusion mistakes.
