Answer:
The correct answer is 15.
Step-by-step explanation:
A survey is conducted of 100 Enormous State University students.
Number of students who enjoy only house music according to the question are 25 students.
Number of students who enjoy classical music according to the question are given to be 25.
Number of students who enjoy rock music according to the question are given to be 20.
Number of students who enjoy both rock and classical music according to the question are given to be 5.
Number of students who enjoyed only rock music are given by 20 - 5 = 15.
Thus 15 students enjoy rock and did not enjoy classical music.
