I ran across these problems on this website and thought they might be of interest. We will give you the solutions tomorrow. www.indiana.edu/~bobweb/Handout/d4.ips.htm
1. Prisoner: A prisoner was attempting to escape from a tower. He found in his cell a rope, which was half long enough to permit him to reach the ground safely. He divided the rope in half and tied the two parts together and escaped. How could he have done this?
2. Hole: How can you cut a hole in a 3 x 5 card that is big enough for you to put your head through?
3. Twins: Marsha and Marjorie were born on the same day of the same month of the same year to the same mother and the same father – yet they are not twins. How is that possible?
4. Children:. Three women – Joan, Dana, and Sandy – have among them three children – Sam, Traci, and David. Sam likes to play with Dana’s son. Sandy occasionally baby-sits for Joan’s children. Who is Traci’s mother?
