I think Precision is defined as intersection of relevant documents and retrieved documents divided by retrieved documents.

In this question there are 20 relevant documents and only 10 documents are retrieved (50-40), which is divided by total retrieved documents which is 50. ie., 10/50 =1/5 ie., 20% precision.

This will become easy to understand when diagrams are drawn.
