The Hardest Riddles With Answers
The Missing Dollar Riddle
Riddle:
Three friends stay in a hotel room that costs $30. Each pays $10.
Later, the hotel manager realizes the room should have cost only $25 and gives the bellboy $5 to return.
The bellboy keeps $2 and gives each guest $1 back.
Now each guest paid $9, totaling $27.
The bellboy kept $2.
$27 + $2 = $29.
Where is the missing dollar?
Answer:
There is no missing dollar.
The mistake comes from adding the bellboy’s $2 to the guests’ $27. The $27 already includes the $2 kept by the bellboy.
Breakdown:
- Hotel receives: $25
- Bellboy keeps: $2
- Guests get back: $3
Total = $25 + $2 + $3 = $30
