Answer 1

Answer:

72%

Step-by-step explanation:

10% of fee paying students exempt from increase

=> 90% of fee paying students pay full fee

So

full fee paying students

= 90% of ( fee paying students )

= 90% of ( 80% of students)

= 90% × ( 80% × number of students )

= 0.9 × 0.8 × number of students

= 0.72 × number of students

= 72% × number of students

= 72% of students
