$\huge\boxed{\fcolorbox{black}{pink}{Answer}}$

Let no of boy = x

Let no of boy = x

And no of girls = y

According to question

=> y = 2/5 x

=> 5y = 2x

=> 5x - 2y = 0 [ Equation 1]

☆___ x + y = 35[ Equation 2]

Multiply 5 in equation 1 and subtract by equation 1

5x + 5y = 175

5x - 2y = 0

After solving,

=> 7y = 175

=> y = 25

putting the value in equation 1

5x - 50 = 0

x = 10
