Riddle 1: There’s no missing dollar. The calculation is incorrect. The friends paid a total of $27 ($25 for the room + $2 for the bellhop).

Riddle 5: Banana (it’s the only fruit)
Riddle 6: The German owns the fish.
Riddle 7: Turn on switch 1 for a few minutes, then turn it off. Turn on switch 2 and immediately enter the room. The bulb that’s on is controlled by switch 2. The bulb that’s off but warm is controlled by switch 1. The remaining bulb is controlled by switch 3.
Riddle 8: Two weighings. Divide the coins into groups of 3, 3, and 3. Weigh two groups. If they balance, the heavier coin is in the unweighed group. If they don’t balance, the heavier coin is in the heavier group. Repeat the process with the group of 3.
Riddle 9: The victim should say, “I will be hanged.” If this statement is true, he will be shot (breaking the killer’s promise). If it is false, he will be hanged (again, breaking the promise).
