Answer 2

Answer:

10

Step-by-step explanation:

let the number of boys be Y

so the number of girls =2/5 x Y

that is equal to 2Y/5

now it is given that total students=35 so,

number of boys + number of girls= total number of students

that is,

Y +2Y/5=35

(5Y+2Y)/5=35

7Y/5=35

Y=35x5/7

Y=25

number of girls=35-Y

=35-25

=10
