Question

The number of boys and girls in a class are in the ratio 5 : 4. If the number of boys

is 9 more than the number of girls, then find the total strength ?​

Answer 1

$\Huge \bf \over \rightarrow\mid\mathcal {\underline{ \red{Answer}}} \mid$

Let us assume number of boys be 5y and the number of girls be 4y.

According to the question:

$\large\bf\implies{\underline{\blue{5x - 4x = 9}}}$

$\large\bf\implies{\underline{\green{x = 9}}}$

• Number of boys = 5x = 5 x 9 = 45 boys.

• Number of girls = 4x = 4 x 9 = 36 girls.

Answer 2

Answer:

Let the no. of boys be 5x and no. of girls be 4x

given 5x - 4x= 9  

x=9  

therefore :

No. of boys = 9 x 5 = 45

Number of girls = 4x = 4 x 9 = 36 girls.
