The Candy Store Riddle

There are two fathers and two sons. They walk into a candy store and each buys a candy bar for 50 cents.
The total for all of the candy bars was $1.50. How is that possible?

Answer: They’re three people: a grandfather, his son, and his grandson.

Explanation:
The group includes two fathers (grandfather and father) and two sons (father and grandson), but there are only three people, so 3 × $0.50 = $1.50.
