The points A and B represent numbers on a number line as shown below :
25000 A 39000 B 61000
The distance between the points A and B is—

The correct option is 22000 units.

Let us analyze the given number line and determine the values of points A and B step-by-step.

Step 1: Understand the given positions on the number line.
The sequence of points on the number line is given as:
25000, A, 39000, B, 61000

Step 2: Find the value of point A.
Point A is situated directly in the middle between 25000 and 39000.
The total distance between 25000 and 39000 is:

$39000-25000=14000$

Since there are 2 equal divisions (gaps) between 25000 and 39000:
Each division represents:

$\frac{14000}{2}=7000$

Therefore, the value of point A is:

$A=25000+7000=32000$

Step 3: Find the value of point B.
Point B is situated directly in the middle between 39000 and 61000.
The total distance between 39000 and 61000 is:

$61000-39000=22000$

Since there are 2 equal divisions between 39000 and 61000:
Each division represents:

$\frac{22000}{2}=11000$

Therefore, the value of point B is:

$B=39000+11000=54000$

Step 4: Calculate the distance between point A and point B.
The distance between A and B is given by subtracting the value of point A from point B:

$\text{Distance}=B-A$

$\text{Distance}=54000-32000=22000\text{units}$

Thus, the distance between the points A and B is 22000 units.
