Official Solution:
Students with a perfect score in Math = 20 percent of 80 = 16 students.
Students with a perfect score in English = 30 percent of 80 = 24 students.
Students with a perfect score in both = 10 percent of 80 = 8 students.
Therefore:
Students with a perfect score only in Math = Math - Both = 16 - 8 = 8 students.
Students with a perfect score only in English = English - Both = 24 - 8 = 16 students.
Correct answer:
Perfect Score in only Math "8"
Perfect Score in only English "16"
