Answer:

Total number of students = 200

The number of girls  = 90

Step-by-step explanation:

Girls = 45%

Boy = (100 - 45)% = 55%

Let the total students = x

Number of boys = 110

55% of x = 110

 [tex]\frac{55}{100}*x = 110\\\\ x = 110*\frac{100}{55}\\\\ x = 10 * \frac{100}{5}\\\\[/tex]

  x = 2 * 100

  x = 200 students

Girls = 45% of x

       [tex]= \frac{45}{100}*200[/tex]

        = 45 * 2

Girls = 90
