HOPE THIS WILL HELP YOU...PLEASE MARK BRAINLIEST

Step-by-step explanation:

Let the number of girls be x

No. of boys = x + 11

ATP,

x + (x+11) = 75

x + x + 11 = 75

2x = 75 - 11

2x = 64

x = 32

Answer 2

Let the number of girls in the class be = X

So according to the question the number of boys in the class will be = X + 11

The total number of students in the class = 75

Thus,

X+X+11 = 75

2X = 75-11

2X = 64

X = 32

No of girls = 32

No of boys = 32+11 = 43
