It loses 7 min per 2 hours that pass.

At noon, it will read 12:00 - (6 x 0:07) = 11:18
At 2PM, it will read 11:18 + (2:00 - 0:07) = 11:18 + 1:53 = 13:11

Bill, your method is correct; however, the answer is not right - yet. At this point, we need to take into account that it was 13.11 two hours ago, meaning that the correct time now is 16.00 (I think this is what Mark was implying by "skimming" as well).

Your turn! :)

Here's one in case Pip is too busy or something:

The Five Diners
(Sapphire, Scher, Serena, Mark, IAmNobody)

The five LitNetters listed above had soup and drinks at a round table.
Please answer the following questions:

1. In what order did they sit around the table? (i.e., Who sat where?)
2. What soup did each of them eat?
3. What did each of them drink?

Here are your clues:

The diners chose from the items on this very simple menu:

DRINKS: Beer, Wine, Water
SOUP: Tomato, Onion, Lentil

also...

• Serena is allergic to onion soup, and can't sit next to a bowl of it (much less eat it).
• Sapphire sat to the right of IAmNobody.
• Scher and IAmNobody had the same thing to drink.
• Mark and Serena each drank beer.
• Both Serena and Sapphire had drinks that were different from the drinks had by the people next to them at the table.
• The two people who had tomato soup were not side-by-side.
• The person who had the onion soup sat between the only two wine drinkers.
• Only one person had tomato soup with beer.

Scher, that looks good, but...

...was meant to indicate that Sapphire is sitting in the seat next to IAmNobody (the seat immediately to IAmNobody's right)

Gah, I have been reading that "Serena" :sosp:

Back to the drawing board!

I know, I apologize for that. I thought it would be fun to include some people that'd been involved in the thread most recently, but all the 'S' names confused me too when I was making it.

There, that is correct--didn't take you long to fix it after getting the names straight.

A nice puzzle and well done! (I couldn't figure it out :blush:)

If you aren't familiar with that sort of puzzle, I just googled a website that looks like it might be a good place to learn about that style of puzzle:

http://www.logic-puzzles.org/

They are called logic puzzles, or logic grid puzzles.

EDIT: actually, that website starts off with more difficult puzzles than mine, and the tutorials don't seem very good...

I like logic puzzles.

Here is another quick one:

HO = 23

KD = 15

TA = 21

UW = ?

it is 44

Hang on. Why?

Whoa, I was stumped, and it just now came to me in a flash. (add together the number representing each letter's ordinal position in the English alphabet, and you get the shown sum)
