admin 80% of the students in my class play sport. 45% of them play basketball, 40% play tennis and the rest play volleyball. If 12 students in the class play volleyball, how many students are there in my class? A: 80 B: 90 C: 100 D: 110
BB23 Hint: 100 - 45- 40 = 15% of students play volleyball So, 15/100 * x = 12 x = 80 Now, This 80 is equal to 80% of the class So, 100% = 100 students
