## Task 3 - 180613

Fred, Gerd, Hans, and Ingo are students in classes 6a, 6b, 7a, and 7b, and each of these classes has one of the four students.

In a conversation involving only Fred and the two students from 7th grade, Hans notes that three of the four students read only one of the magazines "alpha" and "technikus," namely Fred, Gerd, and the student from 6a.

The student from 7b, however, reads both "technikus" and the magazine "alpha."

To which class does each of the four students belong according to these statements, and which student reads both magazines "alpha" and "technikus"?
Fred is not one of the two 7th-grade students he talked to. He is also not the student from 6a, as this one is mentioned in the list given by Hans, apart from Fred. Therefore, Fred belongs to $6 \mathrm{~b}$.

According to this list, neither Fred nor Gerd belong to 6a. Since Hans is one of the 7th-grade students Fred talked to, Hans does not belong to 6a either. Consequently, Ingo belongs to 6a. The two 7th-grade students are therefore Gerd and Hans.

The student from 7b cannot be Gerd, as he reads both magazines, while Gerd reads only one. Therefore, Gerd belongs to 7a and Hans to 7b. The student who reads both magazines is thus Hans.
