What will come in the place of question (?) mark in following the question:

$?+16\times 40=320-8\times 5$

The correct option is -360.

To find the value that comes in place of the question mark ($?$), we need to solve the given algebraic equation step-by-step using standard order of operations (BODMAS/PEMDAS).

The given equation is:

$?+16\times 40=320-8\times 5$

Step 1: Perform the multiplication on both sides of the equation.

On the left-hand side, calculate:

$16\times 40=640$

On the right-hand side, calculate:

$8\times 5=40$

Now, substitute these values back into the equation:

$?+640=320-40$

Step 2: Simplify the right-hand side.

Subtract 40 from 320:

$320-40=280$

So the equation becomes:

$?+640=280$

Step 3: Isolate the question mark ($?$).

Subtract 640 from both sides of the equation:

$?=280-640$

$?=-360$

Therefore, the value that replaces the question mark is -360.
