What will come in the place of the question mark (?) in the following equation, if '+' and '÷' are interchanged and '×' and '–' are interchanged?
$16-33+11÷22\times 5=?$

The correct answer is 65 (Option 1).

We are given the mathematical equation:

$16-33+11÷22\times 5=?$

According to the instructions, we need to interchange the signs as follows:
• '+' and '÷' are interchanged
• '×' and '–' are interchanged

Replacing the signs in the original equation, we get the new expression:

$16\times 33÷11+22-5$

Now, follow the BODMAS rule (Brackets, Orders, Division/Multiplication, Addition/Subtraction) to solve step-by-step:

Step 1: Perform Division
Divide 33 by 11:

$33÷11=3$

Substituting this back into the expression:

$16\times 3+22-5$

Step 2: Perform Multiplication
Multiply 16 by 3:

$16\times 3=48$

Substituting this value back into the expression:

$48+22-5$

Step 3: Perform Addition
Add 48 and 22:

$48+22=70$

Substituting this value back into the expression:

$70-5$

Step 4: Perform Subtraction
Subtract 5 from 70:

$70-5=65$

Thus, the value in place of the question mark (?) is 65.
