Question

The ratio of the number of boys and girls in a class is 2:3. Find the number of boys and girls in the class if the number of students in the class is 45.

Answer 1

Answer:

no. of boys = 2×9 = 18

no. of girls = 3×9 = 27

Step-by-step explanation:

let no .of boys = 2 x

and no. of girls = 3 x

total students = 45

⇒2 x+3 x = 45

⇒ 5 x = 45

⇒x = 9

Answer 2

HEY MATE,

Answer:

Ratio is 2:3 so let the no. of boy be 2x and no. of girls be 3x:

⇒ 2x+3x=45

⇒ 5x=45

⇒ x=9

Putting the value of x in the ratio of boys and girls:

⇒2x=2×9=18 boys

⇒3x=3×9=27 girls

∴Number of boys and girls in the class of 45 students = 18 & 27 respectively.

Boys = 18

Girls = 27
