Answer:
Total number of students = 50 students.
Step-by-step explanation:
Total number of books = number of books * frequency
1 * 3 = 3
2 * 5 = 10
3 * 12 = 36
4 * 25 = 100
5 * 4 = 20
6 * 1 = 6
Total number of books = 3 + 10 + 36 + 100 + 20 + 6
Total number of books = 175 books.
Now, to find the total number of students;
Total number of students = summation of frequency
Total number of students = 3 + 5 + 12 + 25 + 4 + 1
Total number of students = 50 students.
