NPR Sunday Puzzle (Nov 20, 2011): Food Item, Saying and Person's Name

NPR Sunday Puzzle (Nov 20, 2011): Food Item, Saying and Person's Name:

Q: Name a food item. Divide this word in half. Take the second half followed by the first half twice, and you'll get a familiar saying. If you take the second half twice (followed) by the first half, you'll name a well-known person. What are the food item, saying, and person's name?

I vote for the food item being incomplete, but I guess if enough people vote against me, I'll rescind my complaint.

Edit: My hint was "nays" which when added to the food item (mayo) gives the full name (mayonnaise).

A: Food Item: Mayo(nnaise)
Saying: Yo' Mama!
Person: Yo-Yo Ma

NPR Sunday Puzzle (Nov 13, 2011): What Comes Next?

NPR Sunday Puzzle (Nov 13, 2011): What Comes Next?:

Q: What number comes next in the following series: 2, 4, 6, 9, 11, 15, 20, 40, 51*, 55*, 60 and 90?

See, I thought I had the answer to this, but if so, there are a couple numbers missing.

*Update: The consensus seems to be that Henry Hook and Will Shortz overlooked a couple terms in the sequence and it should be 2, 4, 6, 9, 11, 15, 20, 40, 51, 55, 60 and 90. Hopefully everyone is able to solve it now with the corrected wording. If anyone has direct access to Will's email, perhaps they could ask for a similar correction to the puzzle on the NPR website.

Will Shortz has confirmed (see his comment) that he extended Henry Hook's original series (2, 4, 6, 9, 11, 15, 20) and in the process overlooked the numbers above. The NPR website has been updated as well. Thanks to everyone that helped clear this up.

Edit: My hint was "See, I..." which sounds like CI which is 101 in Roman numerals

A: 101 is next in the sequence. When represented as Roman numerals, each number in the series requires exactly two letters (II, IV, VI, IX, XI, XV, XX, XL, LI, LV, LX, XC, CI...)

NPR Sunday Puzzle (Nov 6, 2011): Count the Equilateral Triangles

NPR Sunday Puzzle (Nov 6, 2011): Count the Equilateral Triangles:

Q: Take 15 coins. Arrange them in an equilateral triangle with one coin at the top, two coins touching below, three coins below that, then four, then five. Remove the three coins at the corners so you're left with 12 coins. Using the centers of the 12 coins as points, how many equilateral triangles can you find by joining points with lines?

Minnesota is the land of 10,000 lakes, but I know the answer is much smaller than that.

Edit: My hint points to a shorter form of Minnesota, namely the abbreviation MN. That's also the abbreviation for Manganese (Mn) which has an atomic number of 25.

A: 25 equilateral triangles total (see the video for details).

13 small triangles pointing up or down

4 medium triangles pointing up or down

6 medium triangles pointing left or right

2 large triangles at a slight angle

NPR Sunday Puzzle (Oct 30, 2011): This Singer Keeps Company with a Logo?:

Q: Name a well-known singer. Drop the first and last letters of the singer's first name and you'll get the letters of a well-known company. Drop the first and last letters of the singer's last name, and you'll identify the logo that the company is classically known for. Who is the singer and what's the company?

Musical clue: Adele & Lil Wayne

Edit: There were two clues in my answer. First I had an ampersand (&), hinting at the additional symbol needed in the company name. Second if you combine Adele and Wayne you get "Adele Wayne". Patti LaBelle played Adele Wayne, the mother of Dwayne Wayne on A Different World.

A: Patti LaBelle --> AT&T + A Bell
