Nurse Container Exchange Problem

Problem Statement

Two nurses possess an equal number of containers filled with pills. The question is: How many containers must the first nurse transfer to the second nurse in order for the second nurse to have four more containers than the first?

Solution

The answer is two containers. When the first nurse gives two containers to the second nurse, she loses two containers, while the second nurse gains the same amount. This transaction creates a net difference of four containers between them.
