Answer:
In a class of 28 students the ratio of girls and boys is 4:3. The number of girls in the class is 16.
Solution:
Let us consider total number of students in the class is “T”.
Let the ratio of the students (Girl and boys) in the class is G: B.
Given that total number of students in class (T) = 28
From question, given that ratio of girls and boys is 4:3. We can write this ratio as,
Number of girls (G) = 4x and number of boys (B) = 3x
We have to find the number of girls in class. The total number of girls present in the class is given as ,
[tex]G = T \times \frac{G}{G + B}[/tex]
The total girl students present in the class G = [tex]28 \times \frac{4 x}{4 x + 3 x} = 28 \times \frac{4 x}{7 x}[/tex]
= [tex]28 \times \frac{4}{7} = 4 \times 4 = 16[/tex]
Hence the total number of girls in the class is 16.
