Answer:
5,000 students (hope this helps!)
Step-by-step explanation:
3250 students passed in both subjects
x is the percentage of students that passed in both subjects
total=100%
Passed students=100-15(failed students)=85
85 is the passed students so
passed students in both subjects x= 80+70-85=65
Now x=65
65% of total students=325
.°. Total students = 3250×100/65=5000
Ans. There were a total of 5000 students.
