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
