What will come in the place of question mark (?) in the given expression?
$450\times 30+1500\times 20=?\%\times 43500$

The correct answer is 100 (Option 1).

Let us solve the given mathematical expression step-by-step to find the value that replaces the question mark (?).

The given equation is:

$450\times 30+1500\times 20=?\%\times 43500$

Let the unknown value represented by the question mark (?) be x.

Rewriting the equation with x:

$450\times 30+1500\times 20=\frac{x}{100}\times 43500$

Step 1: Simplify the Left-Hand Side (LHS)

First, calculate the individual multiplication terms on the LHS:

$450\times 30=13500$

$1500\times 20=30000$

Now, add these two products together:

$\text{LHS}=13500+30000=43500$

Step 2: Simplify the Right-Hand Side (RHS)

Simplify the percentage expression on the RHS:

$\text{RHS}=\frac{x}{100}\times 43500=x\times 435$

Step 3: Equate LHS and RHS to solve for x

Set the simplified LHS equal to the simplified RHS:

$43500=435\times x$

Solve for x by dividing both sides by 435:

$x=\frac{43500}{435}$

$x=100$

Thus, the value coming in place of the question mark (?) is 100.
