A while ago I was reading Malcolm Gladwell's Blink and I was taken with two logic puzzles that readers of this blog might enjoy. They are found on pages 120 and 121 of the book respectively.
1. A man and his son are in a serious car accident. The father is killed, and the son is rushed to the emergency room. Upon arrival, the attending doctor looks at the child and gasps, "This child is my son!" Who is the doctor?
2. A giant inverted steel pyramid is perfectly balanced on its point. Any movement of the pyramid will cause it to topple over. Underneath the pyramid is a $100 bill. How do you remove the bill without disturbing the pyramid?
Answers below the fold...
1. The doctor is the boy's mother.
2. Destroy the $100 bill in some way - tear it or burn it.
