Question -:
The ratio of boys and girls in a classroom is 2 : 3 respectively. If the total number of children is 20. How many boys are there in the class ?
Explanation -:
In this question we are provided with the ratio of boys isto girls that is 2 : 3 it is also given that total number of children are 20. We are asked to calculate number of boys.
Let us assume the number of girls as 3x and number of boys as 2x.
Total number of children = 20
3x + 2x = 20
Boys = 2 × 4 = 8
Girls = 3 × 4 = 12
- Hence 8 boys and 12 girls are there in the classroom.
