In a class of 30 students, 18 students like math and 15 students like science. If 7 students like both math and science, how many students like neither math nor science?

✓ Correct Answer: Option B

Students who like only math = 18 - 7 = 11. Students who like only science = 15 - 7 = 8. Total students liking at least one subject = 11 + 8 + 7 = 26. Students who like neither = Total students - Students liking at least one = 30 - 26 = 4.
