Correct Answer :

Option C

60

Solution :

The correct answer is 60.

We are given the mathematical equation:

35×96-8+3÷11=?

According to the instructions, we need to interchange the mathematical operators as follows:

• '+' and '×' are interchanged
• '-' and '÷' are interchanged

Replacing the original operators in the given equation with their interchanged counterparts, we get:

35+96÷8×3-11=?

Now, solve the expression following the standard order of operations (BODMAS / PEMDAS rule):

Step 1: Perform Division

96÷8=12

Substituting this back into the equation:

35+12×3-11=?

Step 2: Perform Multiplication

12×3=36

Substituting this back into the equation:

35+36-11=?

Step 3: Perform Addition and Subtraction

35+36=71

71-11=60

Therefore, the value that replaces the question mark (?) is 60.
