Answer 1

Answer:

The number of girls in the class is 27.

Step-by-step explanation:

The total number of students in the class is, N = 47.

Let the number of boys be x.

Then the number of girls is: x + 7.

Compute the number of boys as follows:

$x+x+7=47\\2x=40\\x=20$

The number of girls is:

$n(Girls)=47-20=27$

Thus, the number of girls in the class is 27.
