Here are the problems again and the solutions for the insight problems for May 22, 2014:
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?
Solution: Unwind the rope and tie the ends together
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?
Solution: Cut a spiral out and unwind it
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?
Solution: They are triplets
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?
