A scientist is experimenting with bacteria that are one micron in diameter and that reproduce by dividing every minute into two bacteria. At 12:00 PM, he puts a single organism in a container. At precisely 1:00 PM, the container is full.
At what time was the container half full?
How big was the container?
An investor trading through a discount stock broker that charges $10.00 Dollars per transaction bought 200 shares of Vola Tile Corporation at $50.00 Dollars per share. The stock quickly increased in value by 50%, but then lost 40% of its value. The investor sold the stock.
How much money did the investor gain or lose?
A valuable painting was stolen from the Liar's Club, but the police are having a hard time identifying the culprit because every statement made by a member of the Liar's Club is false. Only four members visited the club on the day that the painting was stolen. This is what they told the police:
Ann: None of us took the painting. The painting was here when I left.
Bob: I arrived second. The painting was already gone.
Chuck: I was the third to arrive. The painting was here when I arrived.
Tom: Whoever stole the painting arrived before me. The painting was already gone.
Who of these four liars stole the painting?
i'm too tired after work to do this one!

so the first 2 were easy enough, but for the third one, the answer was Ann as a few people have said - here's why step by step
Since every statement is false, let us convert them into true statements, and number each statement:
Ann: 1) One of us took the painting. 2) The painting was gone when I left.
Bob: 3) I arrived first, third, or fourth. 4) The painting was still here.
Chuck: 5) I arrived first, second, or fourth. 6) The painting was gone when I arrived.
Tom: 7) Whoever stole the painting arrived after me. 8) The painting was still here.
According to statement #7, Tom is not the thief. #8: Since the painting was there when Tom arrived, he could not have been the last to arrive. Tom must have gone there first, second, or third. #6: The painting was gone when Chuck was there, so he didn't arrive first. #5: So Chuck got there second or fourth. #4 and #8: As two other members (Bob and Tom) arrived to see the painting, Chuck didn't get there second, either. So Chuck arrived fourth. #3: This means Bob arrived first or third. #2: Since the painting was gone when Ann left, she didn't arrive first. Otherwise, no member after her would have seen the painting. So Ann went there second or third and Chuck arrived fourth. But since two other members (Bob and Tom) saw the painting when they arrived, Ann didn't go there second, either. So Ann arrived third. #3: Therefore, Bob arrived first, and Tom arrived second.
In summary, Bob arrived first. Tom got there next and the painting was still there, so Bob was not the thief, and neither was Tom. When Ann arrived, the painting was still there, but it was gone when she left. So Ann was the one who stole the painting. Chuck arrived last and discovered that the painting was gone.

1. assuming the bacteria are of a circular shape regardless of how that shape fluxuates it will still have the same area therefore the size of the container is:
For every minute that passes you increase the power by one.To begin there is one bacteria present so is represented by 2^0. After 1 minute the number of bacteria is 2 or otherwise 2^1. After 60 mins the number of bacteria is 2^60 or 8192.
Every bacteria is one micron in diameter so the resulting area is then Pi*d or Pi*1 microns^2
therefore after 60 mins the total area of the microns is equal to the total area of the container which is: 8192*Pi microns^2
3. Cant be Chuck painting wasn't there when he arrived.
Ann is a grey area however examining the exact phrasing (or more the opposite of) we can assume the painting was stolen BEFORE she left.
Tom and Bob are the only likely suspects because the painting was present when they both arrived however I'm more inclined to believe Bob stole it simply because reversing Toms statement in the literal sense indicates the painting was there when he arrived but the culprit arrived after him. This satisfies the reverse statement of Bobs which claims the painting was there when he arrived and that he either arrived 1st, 3rd or last. It fits the story if he arrived 3rd. Ann 1st arrived, Tom next, Bob (painting stolen), Ann leaves, Chuck arrives!!
please correct me if im wrong theres nothing i love more than heated logical debate!!

They may not be circular as a micron implies they are cubic. :-)
They amy pack in different ways.
There is a mistake in logic in the question, the answer can be either tom or ann, nobody else.
If you take it that the sentences have to be the opposite of what is said, Ann is the only answer.
This all asssumes they can not be there at teh same time, as this would make it unsolvable.
