Marco is in elementary school. His father is 30 years older than marco, and his mother is 4 years younger than his father. The ages of marco, his father, and mother are all prime numbers. What are their ages?
:
The only age in elementary school that is a prime number is 7
Assume Marco is 7
then father is 37, a prime number
However, Mom is 33, not a prime number

A bad problem
