If + means - , - means x , x means ÷ , ÷ means +, then what will come in place of the question mark (?) in the following equation?
8-21×3÷75+13=?

The correct option is 118.

To solve this equation, we first need to substitute the original operators with the new operators as defined in the question:

• + means -
• - means ×
• × means ÷
• ÷ means +

Original Equation:

$8-21\times 3÷75+13=?$

Substituted Equation:

$8\times 21÷3+75-13$

Now, we evaluate the expression step-by-step using the BODMAS/PEMDAS rule (Division and Multiplication first, followed by Addition and Subtraction):

Step 1: Perform Division

$21÷3=7$

The expression becomes:

$8\times 7+75-13$

Step 2: Perform Multiplication

$8\times 7=56$

The expression becomes:

$56+75-13$

Step 3: Perform Addition

$56+75=131$

The expression becomes:

$131-13$

Step 4: Perform Subtraction

$131-13=118$

Hence, the value coming in place of the question mark (?) is 118.
