What will come in the place of question (?) mark in following the question:
30% of 500 + 320 = 260 + ?

To find the value that comes in place of the question mark (?), we can set up the equation based on the given problem statement and solve it step-by-step.

The given equation is:

$30\%\text{ of }500+320=260+?$

First, let's calculate the value of "30% of 500". Recall that "percentage of" means multiplying the percentage value by the number:

$30\%\text{ of }500=\frac{30}{100}\times 500$

Simplifying this calculation:

$30\%\text{ of }500=30\times 5=150$

Now, substitute this value back into the original equation:

$150+320=260+?$

Next, add the numbers on the left-hand side of the equation:

$150+320=470$

This gives us the simplified equation:

$470=260+?$

To isolate the question mark (?), subtract 260 from both sides of the equation:

$?=470-260$

$?=210$

Therefore, the value that should replace the question mark is 210.
