Question
The table below shows the number of girls, the percentage of boys out of the total number of students, and the percentage of students who attended a seminar in four different schools.
| Schools | Number of girls | Percentage of boys out of total students | Percentage of students attended the seminar |
|---|---|---|---|
| P | 120 | 40\% | x\% |
| Q | 80 | 80\% | 40\% |
| R | 35 | 65\% | y\% |
| S | 50 | 75\% | 60\% |
Note:
- is 5% of the average number of students in schools P and Q.
- is 12.5% of the total students who attended the seminar in school Q.
- Total students = total girls + total boys.
- Total students = students attended the seminar + students not attended the seminar.
In school E, the ratio of boys to girls is the same as in school P, and the number of boys in E is 20% more than the number of girls in school R. Find the number of girls in school E.
