Today’s puzzle for the clever ones

Mr. and Mrs. Martin have four daughters. Each girl has a brother.

How many members are there in the Martin family in total?

✅ Steps to reasoning:

Mrs. Martin → 1 person

4 girls → 4 people

Each girl has a brother.

This does not mean there are four brothers.

If each girl has the same brother, then there is only one brother.
