Answer 2

Let the number of girls be x.

Now boys are 11 more than girls, so :

Number of boys = x+11

x+x+11= 75 (Total number of students is 75 as given in question}

2x+11 = 75

2x = 75 - 11 {+11 becomes -11 when shifted to the other side of the equation}

2x= 64

x = $\frac{64}{2}$

x= 32

Number of girls = x = 32 girls

Number of boys = x+11 = 32+11 = 43

Therefore, there are 32 girls and 43 boys in the class.
