Hello, americo74!
\(\displaystyle 1200\) families have cars.
\(\displaystyle 1300\) families have bicycles.
Adding them we have: .\(\displaystyle 1200\,+\,1300\:=\:2500\) families.
Since there are only 2000 families in the town,
. . there must be an "overlap" of at least \(\displaystyle 500\) families.
[If there are townspeople who own <u>neither</u> a car nor a bicycle,
. . the overlap is even larger.]
