Question

Find the difference between the number of students absent from the month of July to August.

A. 1
B. 2
C. 3
D. 1

Answer 1

Hint: We first find the axes and also find out the variables they represent. Then we find the individual value of the number of absentees in those two mentioned months. We find the difference between the number of students using methods of subtraction.

Complete step-by-step solution:
In the given graphical representation, there are two axes. The X-axis represents the months. There are 12 entries, January to December. The Y-axis represents the number of absentees.
We need to find out the difference between the number of students absent during the month of July to August.
We first find out the number of students absent in those two months individually.
From the marking of the individual bar graphs, we can see that the number of students absent in the month of July is 12.
Similarly, we find that the number of students absent in the month of August is 15.
Now we find the difference between the number of students absent from the month of July to August.
We use the process of subtraction to find the solution.
The difference will be $15-12=3$.
So, the difference between the number of students absent during the month of July to August is 3. The correct option is (C).

Note: If the individual values of those months are not mentioned then we need to draw a perpendicular line from the top of the bars of those individual months on the Y-axis to find out the values. The line will touch the axis at a fixed point and that will help to find the exact value.
