Question

Each student must take part in at least one sport, either football or basketball. In a class of 80 students, 60 play football and 40 play basketball. How many student play football only?

Answer 1

40

60+40 is 100. This means that 100 enrollments in sports have been made. However, only 80 students exist, meaning 20 students are enrolled in both sports. If we subtract 20 from the 60 who play football, this leaves 40 who only play football.
