Puzzle – 4: “What day do you go back to school, Horace?” asked his grandmother one day.

“Well,” Horace replied, “Nine days ago, the day before yesterday was three weeks before the second day of term.”

If Horace had this conversation on a Sunday, what day of the week did he start school?

Answer: The reasoning runs as follows:

Today is Sunday.

So seven days ago was Sunday too. That means that NINE days ago was Friday.
