Question

lthe ratio between the number of boys and girls in 8th cladd of a particular govt. school if 2:3 if total a students in the cladd are 50 then find the number of boys and girls​

Answer 1

Answer

Let the ratio of boys be 2x

Let the ratio of girls be 3x

A/Q

2x+3x = 50

5x = 50

x = 50/5

x = 10

Boys = 10×2 = 20

Girls = 10 ×3 =30

hence number of boys in class 8 is 20 and number of girls in class 8 is 30

Answer 2

Answer:

no. of boys = 20

no. of girls = 30

Step-by-step explanation:

Given ratio = 2:3

Total strength = 50

Sum of ratio terms =(2+3)=5

:. No. of boys =

$( \frac{2}{5} \times 50)$

= (2×10)

=20

:.No. of girls =

$( \frac{3}{5} \times 50)$

= (3×10)

=30

Hence, in that class the no. of boys is 20 and no. of girls is 30 respectively.
