Decorating With Tiles

You are decorating for spring and you’ve found a bargain. A huge box of beautifully decorated tiles, enough to provide a border in two rooms. You really can’t figure out how to arrange them. If you set a border of two tiles all around, there’s one left over. If you set three tiles all around or four or five or six there’s still one tile left over. Finally you try a block of seven tiles for each corner and you come out even. What is the smallest number of tiles you could have to get this result?

301. This is the smallest number that even divides by 7, but when divided by 2, 3, 4, 5, and 6 gives you one left over.

Alphonso and Sadie

Alphonso and his sister Sadie are entering the airport to meet their mother when Sadie gasps in surprise and says to her brother, “You see that man in the crowd over there?”

Alphonso replies, “It’s Bernie. I don’t believe it. Let’s go introduce ourselves.”

Neither of them had ever met Bernie before. They’d never seen a picture or painting of him, nor was he a famous celebrity.

How was this possible?

Alphonso was born as a twin, but he was separated from his twin brother at birth. Bernie is Alphonso’s identical twin, which is how Sadie was able to recognize him in the crowd.

This is kind of a cheat, because there are probably other possible explanations. But we can’t have everything :)

Four Walls and a Bird

A man walks out of a house that has four walls all facing north. A bird walks past him. What kind is it?

A penguin. If all four walls face north the house must be at the southernmost point of the earth. Really, any native antarctic bird would work.

This brain teaser is quite similar to the guy whose house walls face south and sees a bear, then you’re asked the color of the bear. The bear would be white (a polar bear) as they’re the only bears indigenous to the north pole. A lawyer would claim it’s all circumstantial evidence and the bear could be an imported brown bear. The lawyer makes a valid point.
