Lazy Daughter
A wealthy wise old woman feared that her daughter was lazy and, as a result, rather stupid. When the old woman died, her will stipulated that her assets were to be liquidated and a check was to be written for the full amount.
The check was to be placed in one of three envelopes. The other two envelopes would contain a blank piece of paper. If the daughter could determine from the writing on the envelope which envelope contained the check, she would inherit her mother’s fortune. Otherwise, the fortune would go to the old woman’s favorite charity for animals.
The daughter was not allowed to touch the envelopes. Her decision had to be made based on the writing on the envelopes. The daughter was told that only one envelope had a true statement and that the other two statements were false.
The envelopes had the following writing:
1. This envelope does not have the check.
2. This envelope has the check.
3. The second envelope does not have the check.
Which envelope should the daughter pick?

Riddle AnswerThe Missing Dollar
Three men go to stay at a hotel and they are charged $30 for the room.
They split the cost with ten dollars each.
Later the manager finds out that the rate is $25 and gives the bellboy $5 to return to the guests. On the way to the room the bellboy reasons that $5 would be difficult to split among three people so he pockets $2 and gives $1 to each person.
Now each person paid $10 and got back $1. So they paid $9 each, totalling $27. The bellboy has another $2, adding up to $29. Where is the missing dollar?
