Problem Analysis

In this problem, we are given that 45 new desks were placed evenly in three classes. Then, 3 desks were removed from one class and 2 desks were removed from another class. We need to determine how many desks are now in each class.

Solution

Let's break down the problem step by step:

1. Initially, there were 45 new desks placed evenly in three classes. This means that each class had 45/3 = 15 desks. 2. From one class, 3 desks were removed, and from another class, 2 desks were removed. This means that each class now has 15 - 3 = 12 desks.

Therefore, after removing 3 desks from one class and 2 desks from another class, each class now has 12 desks.
