## Task 1 - 260511

The girls Grit, Regina, and Beate each wear a one-color blouse. Of these three blouses, one is yellow, one is red, and one is blue.

Grit notes that none of the girls is wearing a blouse of the color that has the same initial letter as the girl's first name.

The girl with the red blouse responds: "I hadn't noticed that, but you're right. Grit!"

Which blouse does each girl wear?
From Grit's statement it follows:

(1) Grit's blouse is not yellow.

(2) Regina is not wearing the red blouse.

(3) Beate is not wearing the blue blouse.

Since the girl with the red blouse is not Grit (as she had not yet noticed Grit's statement), it follows: (4) Grit's blouse is not red.

From (1) and (4) it follows that Grit is wearing the blue blouse. Then, because of (2), Regina must be wearing the yellow blouse. It follows further that Beate is wearing the red blouse.
