Answer 1

Answer:

Number of girls in the class=10

Answer 2

Ur Query:

In a class of 35 students, the no. of girls is two-fifth of the no. of boys. Find the number of girls in the class

Given :

Total number of students = 35

and no. of girls is ⅖ of the no. of boys.

Let the No. of boys = 'x'

Let the No. of girls =$\frac{2}{5}x$

Now solution,

Total student = 35

$\therefore x + \frac{2}{5} x = 35$

$\frac{5x + 2x}{5} = 35 \\ \frac{7x}{5} = 35 \\ x = \frac{35 \times 5}{7} \\ x = 25$

No. of boys = x = 25

No. of girls = ⅖x = $\frac{2}{5}x$ = $\frac{2}{5} \times 25$

$= 2 \times 5 = 10$

No. of girls = 10
