Three boxes (Red, Blue, Green) arranged left-to-right contain a book, a coin, and a key (one item per box). 1. The key is in the Green box. 2. The coin is in a box immediately to the left of the book. Which item is in the Red box?
The coin
The Green box contains the key. That leaves Red (position 1) and Blue (position 2) for the coin and book. Since the coin is immediately to the left of the book, the coin must be in Red and the book in Blue.
