Answer:
Girls =66
Boys=54
Boys percentage=45%
Explanation:
Given that;
There are 120 student
percentage of girls is 55%
let girls be =x
x=percentage* total no 'of students
x=55/100*120
x=66
Boys=total no'of students-no' of girls
=120-66
=54
For boys percentage;
No'of students=boys percentage*total no'of students in the school
54=x/100*120
54=6x/5
6x/5=54 ( LHS to RHS and RHS to LHS)
6x=54*5
x=54*5/6
x=9*5
x=45
Therefore,Girls=66
Boys=54
percentage of boys= 45%
