Question

The number of books in a class library is 17
more than 3 times the number of students
in the class. If 5 students are absent, each
student can borrow exactly 4 books from the
library. Find the number of students in the
class. I know the answer is 37 but please write the method to bring 37 as the answer​

Answer 1

Answer:

37

Step-by-step explanation:

Now assume the no of students in the class to be x

So total no of books = 3x + 17

If 5 students are absent , total no of students = (x-5)

If each student borrows 4 books, then total no of books = (x-5)*4

We also know that total number of books = 3x+17

On equating the above 2 equations

We get 4x -20 = 3x + 17

So x = 37
