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 option is 22.

From the given bar chart, we can extract the values for total students (Boys + Girls) represented by the blue bars and the difference between boys and girls (Boys - Girls) represented by the orange bars:
For School C:
Total students (Boys + Girls) = 48
Difference (Boys - Girls) = 12

For School D:
Total students (Boys + Girls) = 52
Difference (Boys - Girls) = 4

First, let us calculate the number of absent boys in School C:
Total number of students in School C = 48
Number of absent students in School C = 25% of 48

$\text{Absent students in C}=\frac{25}{100}\times 48=12$

Given that the number of absent girls in School C is 10:
Absent boys in School C = Total absent students - Absent girls

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

Next, let us calculate the total number of girls in School D:
Let the number of boys in D be $B_D$ and the number of girls in D be $G_D$.
From the bar chart:

$B_D+G_D=52$ (Equation 1)

$B_D-G_D=4$ (Equation 2)

Subtracting Equation 2 from Equation 1:

$(B_D+G_D)-(B_D-G_D)=52-4$

$2G_D=48$

$G_D=24$

So, the total number of girls in School D is 24.

Finally, we compare the absent boys in School C to the total girls in School D:
Difference = Total girls in School D - Absent boys in School C

$\text{Difference}=24-2=22$

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