Answer 2

Class mark of class interval 10-25 is calculated in the following ways:

First of all we need to take its average by adding this both numbers and then dividing it by 2 as these are only two numbers. (If there were 3 numbers then we would have added it and divided by 3)

Here are the steps:

$= \frac{ 10 + 25}{2}$

$= \frac{35}{2}$

$= 17.5$

Hence, the class interval of 10-25 will be 17.5.
