If + means - , - means x , x means ÷ , ÷ means +, then what will come in place of the question mark (?) in the following equation?
$53+28÷72\times 8-3=?$

The correct option is 52.

To solve this problem, we need to replace the mathematical symbols in the given equation according to the instructions provided:

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

The given equation is:

$53+28÷72\times 8-3=?$

Substituting the new mathematical operators into the equation, we get:

$53-28+72÷8\times 3$

Now, applying the BODMAS/PEMDAS rule (Division and Multiplication first from left to right, followed by Addition and Subtraction):

Step 1: Perform Division ($72÷8$):

$72÷8=9$

The equation becomes:

$53-28+9\times 3$

Step 2: Perform Multiplication ($9\times 3$):

$9\times 3=27$

The equation becomes:

$53-28+27$

Step 3: Perform Addition and Subtraction (from left to right):

$53-28=25$

$25+27=52$

Thus, the value that comes in place of the question mark (?) is 52.
