Let us set up the equation using the given information

Boys = x
Girls = √x
Boys + girls = 42

Equation: x + √x = 42

You can now work out this equation to solve for x, OR reason your way through it. By substituting numbers into the equation. Try 36
36 + √36 = 42
36 + 6 = 42
42 = 42

ANSWER: 36 Boys (and 6 girls)

Hope this helps! God bless!! :)
