Problem Analysis

We are given that there were initially 10 books on each of the three shelves. After adding some more books, the total number of books on the shelves became 62. We need to determine how many books were added to the shelves.

Solution

Let's assume that x books were added to the shelves. Since there were initially 10 books on each shelf, the total number of books on the shelves before adding any books is 3 * 10 = 30.

After adding x books, the total number of books on the shelves becomes 30 + x. According to the problem statement, this total is equal to 62.

Therefore, we can set up the equation:

30 + x = 62

To solve for x, we can subtract 30 from both sides of the equation:

x = 62 - 30

Simplifying the right side:

x = 32

Therefore, 32 books were added to the shelves.

Answer

32 books were added to the shelves.
