Some books are distributed according to the ratio of the number of students in three classes in grade six. There are 42 students in class one, 45 students in class two and 44 students in class three. Class two gets six more books than class one. How many books are there in all

two hundred and sixty-two
Because it's based on the number of people
One class is divided into x books, two classes are divided into x + 6 books
So x: (x + 6) = 42:45
So we have x = 84
So there are 90 copies in class 2, and each of them has two
So the answer is 2 * (42 + 45 + 44) = 262
