The pupils of Paul Tardus tell him the following statements concerning the age of the Elbschiffer and of Hein:
The sum of the ages of Hein, the Elbschiffer and Paul Tardus is bigger than 140 and smaller than 150.
Hein is younger than Paul Tardus, and the Elbschiffer is older than him, but younger than twice as much as the age of Hein.
The difference between the age of the Elbschiffer and the age of Hein is divisible by 7.
The difference between the doubled age of Paul Tardus and the age of the Elbschiffer is divisible by 5.
The sum of the ages of Hein and the Elbschiffer is 90 at least and 100 at most.
After hearing these statements Paul Tardus says: I do not know the ages of the both, but the age of the Elbschiffer is no prime.
The pupils add: If we told you the remainder of the difference between the square of the age of the Elbschiffer and the age of the Elbschiffer itself divided by three, you would know the ages.
Solution code: The ages of the Elbschiffer and of Hein.
