Light one fuse at both ends and, at the same time, light the second fuse at one end. When the first fuse has completely burned, you know that a half hour has elapsed, and, more relevantly, that the second fuse has a half hour left to go. At this time, light the second fuse from the other end. This will cause it to burn out in 15 more minutes. At that point, exactly 45 minutes will have elapsed.

We know that Richard tells the truth on only a single day of the week. If the statement on day 1 is untrue, this means that he tells the truth on Monday or Tuesday. If the statement on day 3 is untrue, this means that he tells the truth on Wednesday or Friday. Since Richard tells the truth on only one day, these statements cannot both be untrue. Therefore, exactly one of these statements must be true, and the statement on day 2 must be untrue.
Assume that the statement on day 1 is true. Then the statement on day 3 must be untrue, from which follows that Richard tells the truth on Wednesday or Friday. Consequently, day 1 is a Wednesday or a Friday. Therefore, day 2 is a Thursday or a Saturday. However, this would imply that the statement on day 2 is true, which is impossible. From this, we can conclude that the statement on day 1 must be untrue.
This means that Richard told the truth on day 3 and that this day is a Monday or a Tuesday. Therefore, day 2 is a Sunday or a Monday. Because the statement on day 2 must be untrue, we can conclude that day 2 is a Monday.
Consequently, day 3 is a Tuesday. Therefore, the day on which Richard tells the truth is Tuesday.

Put the first euro exactly in the middle of the table. Place each next coin "mirrored" to the coin your opponent has just placed: draw an imaginary line from the last coin of your opponent, through the center of the table, and place your coin on that line, exactly as far from the center of the table as your opponent's coin. In this way, you are sure that you can always place a euro and that your opponent is the first one that can no longer place a euro.
Notary Big puts the document in the metal tube, locks the lid with one of his padlocks and sends it to notary Small.
