Mike had spent a week at the station because there was a jumble book sale as part of a “Book Week”. The book dealers (Albert, Clara, Emma, Lotte and Sammy) were present on one day only (Monday, …, Friday).
Each day Mike found a book – about Pythagoras, Thales, Euclid, Archimedes and Aristarch. Mike thought that the prices were reasonable (3,50 €, 4 €, 4,50 €, 5 €, 5,50 €).
1. The book he bought on Thursday was the most expensive.
2. The book dealer Albert set up his stall on Tuesday. His book was more expensive than the one about Thales.
3. The book sold by Clara was not the cheapest.
4. Tghe book about Aristarch was bought on Monday.
5. The book dealer named Emma wanted 5€ for her book.
6. The book about Euclid was just 3,50€ but it wasn’t bought on Wednesday.
7. Mike bought the book about Pythagoras at Lotte’s stall.

When did Mike buy which book at which price and from whom? 6 red points
