In a class of 25 students, 2 students did not borrow any books from the library, 12 students each borrowed 1 book, 4 students each borrowed 2 books, and the rest borrowed at least 3 books. If the average number of books per student was 2, what is the maximum number of books any single student could have borrowed?
Answer/Solution
12
Steps/Work
The total number of books the students borrowed is 25*2=50.
The students who borrowed zero, one, or two books borrowed 12*1+4*2=20 books.
The 7 students who borrowed at least three books borrowed 50-20=30 books.
If 6 of these students borrowed exactly 3 books, then the maximum that one student could have borrowed is 30-18= 12 books.
The answer is E.
