Answer 2

Answer:

The Girls are 10 and Boys are 25 in Number.

Step-by-step explanation:

Gívєn -

Total Students = 35

Number of girls = $\dfrac{2}{5}$ of Boys

Tσ fínd -

Number of Girls and Boys in the Class

Sσlutíσn -

Let the Number be -

• Boys as x
• Girls as $\dfrac{2}{5}x$

As Given in the Question -

$\rule{300}{1.5}$

The total Students are 35.

$\tt{\implies} \: x + \dfrac{2}{5}x = 35$

$\tt{\implies} \: \dfrac{5x + 2x}{5} = 35$

$\tt{\implies} \: \dfrac{7x}{5} = 35$

$\tt{\implies} \: 7x = 35 \times 5$

$\tt{\implies} \: 7x = 175$

$\tt{\implies} \: x = \dfrac{175}{7}$

$\tt{\implies} \: x = 25$

Boys are 25

$\rule{300}{1.5}$

Number of Girls =

$\tt{\implies} \: \dfrac{2}{5} \times x$

$\tt{\implies} \: \dfrac{2}{\cancel5} \times \cancel{25}$

$\tt{\implies} \: 2 \times 5$

$\tt{\implies} \: 10$

Number of girls = 10

$\therefore$ The Girls are 10 and Boys are 25 in Number.
