Friends…!
It is the simplest and less time consuming method, no complicated equations and their solving is required.
The rational between number of boys and girls be x
The ratio of boys to girls in a class is 3:2.
Thus the number of boys are 3x and number of girls are 2x
If the number of boys is 6 more than the number of girls
3x = 2x + 6
3x - 2x = 6
x = 6
The rational is 6, therefore. Number of boys and girls in the class are:
Number of boys 3x = 3 × 6 = 18 boys
Number of girls 2x = 2 × 6 = 12 girls
Answer there are 18 number of boys in the class of 30 students
