The bar shows the total number of students in four schools and it also shows the difference between boys and girls in these schools.

25% of the total students in C are absent and out of that 10 girls are absent. Find the absent boys in C is how many more/less than total girls in D.

The correct answer is 22.


Step 1: Analyze the given bar graph data.
From the given bar graph:
- The blue bar represents the total number of students ($\text{Boys}+\text{Girls}$).
- The orange bar represents the difference between boys and girls ($\text{Boys}-\text{Girls}$).

Step 2: Calculate the total number of girls in School D.
From the graph, for School D:
- Total students ($\text{Boys}+\text{Girls}$) = 52
- Difference ($\text{Boys}-\text{Girls}$) = 4

Adding the two equations gives twice the number of boys:

$2\times \text{Boys}=52+4=56$

Therefore, the number of boys in D is:

$\text{Boys in D}=\frac{56}{2}=28$

Subtracting the number of boys from the total number of students in D gives the number of girls in D:

$\text{Girls in D}=52-28=24$

Step 3: Calculate the number of absent boys in School C.
From the graph, for School C:
- Total number of students = 48

Given that 25% of the total students in School C are absent:

$\text{Total absent students in C}=25\%\text{of}48=\frac{25}{100}\times 48=12$

It is given that out of these 12 absent students, 10 are girls.
Therefore, the number of absent boys in School C is:

$\text{Absent boys in C}=12-10=2$

Step 4: Find the difference between absent boys in C and total girls in D.
We need to calculate how many fewer absent boys in C are compared to total girls in D:

$\text{Difference}=\text{Total girls in D}-\text{Absent boys in C}=24-2=22$

Hence, the number of absent boys in School C is 22 less than the total number of girls in School D.
