The worlds first riddle!

3,7,10, 11,12
When spelled, 'e' is the only vowel.

Oops. That can't be right, or 17 would be in the list.

If he had some, he don't told us!

I love it, you're a funny guy, I wish I had said that.



Dr_bido
3 daughters ages are 9 2 2



How, I hear you ask did Dr_bido arrive at that answer. Well, one way could be:



The data:
A times B times C = 36;
A + B + C = (unknown) house number;

1. The divisors of 36: 1; 2; 3; 4; 6; 9; 12; 18; 36

2. The possible combinations:
1 time 1 time 36 (house number 38)
1 time 2 times 18 (house number 21)
1 time 3 time 12 (house number 16)
1 time 4 times 9 (house number 14)
1 time 6 times 6 (house number 13)
2 times 2 times 9 (house number 13)
2 times 3 time 6 (house number 11)
3 times 3 times 4 (house number 10)

3. The logic: If the house number was 38, 21, 16, 14, 11 or 10, the solution would be CLEAR and the salesman would not have have to inquire. Thus the house number must have been 13. Due to the information that there is only ONE (eldest) daughter, the solution 1 + 6 + 6 can be dropped, since there would be 2 eldest daughters in this case (twins) - and the woman would have said "elder" instead of "eldest".

Thus the correct solution is : 2 + 2 + 9. (so it doesn't matter, what the eldest daughter's name is or what hobby she has, main thing is, she is mentioned.)

Three Nomads count with their fingers, as their ancestors did, the animals of a large herd which trod by them. How many animals can they count and how does their thousands-of-years old counting method work

Thumbs count as fingers.





What is the name for: a metal sheath or tag at the end of a shoelace, ribbon, etc.



What alloy is formed when tin is combined with lead or antimony


What is the largest creature on earth, existing today, without a backbone

Besides humans, there is another animal that has unique fingerprints. What is it

NOMADS
They could use base 2 and each count up to 1023 (finger up is 1, finger down is 0). If they combine their fingers, they can count up to 1073741823.

They could use base 3 and each count up to 59048 (finger up is 2, finger bent at knuckle is 1, finger down is 0). If they combine their fingers, they can count up to 205891132094648.

CREATURE
Does creature include members of the plant kingdom? I've read about some huge undergound fungus that is supposed to be the largest known living thing. It certainly doesn't have a backbone.

Mark enquires, "Does creature include members of the plant kingdom?"

CREATURE: ?'a living organism characterized by voluntary movement'

"huge underground fungus" By (Enid Blighton)


Lets say, "The giant squid is the largest creature without a backbone. It weighs up to 2.5 tons and grows up to 55 feet long. Each eye is a foot or more in diameter.

Mark:
NOMADS
They could use base 2 and each count up to 1023 (finger up is 1, finger down is 0). If they combine their fingers, they can count up to 1073741823.

They could use base 3 and each count up to 59048 (finger up is 2, finger bent at knuckle is 1, finger down is 0). If they combine their fingers, they can count up to 205891132094648.


That beats :

They can count up to 1000 animals with their fingers. The first nomad counts from 1 - 10 . The second counts, how often the first counted to 10, i.e. each finger of the second represents 10. The third nomad finally counts, how often the second used all his fingers (10 fingers of the second = 10 times 10 = 100).
When the third stretched all of his fingers --> 1000.

A farmer wants to fence in as large a garden as possible with 1,000 m of fencing material. He heard that a square format would provide the largest enclosable (rectangular!) area (only demonstrable with differential calculus; otherwise to be seen by trying out with different values of the number). Now a mate at the table reserved for regulars has told him, if he created a circular garden, he would have a still larger fenced-in area.

Is that correct
If so, how much more fenced-in area would he have

I just came by to gloat at the difficult questions, and what do I find!
All done and dusted before lunch. However, this being the season of good will, I seek revenge.

Mark:
FENCE
yes - for a given perimeter, the circle encloses the largest area
17077.47+ square meters.

The range of a square is the quadruple side length a (U = 4 • a; changed over, since U is given: a = U : 4). The side length of a square garden would thus be with a fence length of U = 1,000 m : 250 m. The area of a square is the square of the side length (A = a • a = a² = 250 m • 250 m = 62,500 m²). For calculating the circumference of the circle the diameter has to be multiplied by π (= approx. 3.14) (U = d • π; changed over, since U is given: d = U : π). With the fence length of U = 1,000 m --> d = 1,000 m : 3.14 = 318.47 m. the area of a circle is calculated with the formula: A = π •d² / 4 = 3.14 • 318.47 m • 318.47 m : 4 = 79,617 m². Possibly as having been expected, the round garden is larger, around 17,117 m² or 17,117/ 62,500 = 27.4 % !

Now, this is what I call a ?'Riddle'.


If Mark walks to the station at 3 mph, he misses his train by 1 minute.

If he runs at 6 mph, he has 2 minutes to spare.

What is the distance to the station



After a strong tempest, a large cellar has to be pumped out. 4 pumps with different performances are available:

Alone;
pump A would have to run 30 h ,
pump B 20 h,
pump C 15 h
pump D 10 h
to pump out the whole cellar.
Therefore, all 4 pumps are used at the same time.

After how many hours will the cellar be pumped out


Teddy wants to break into a coat shop. He needs 3 buddies for the coup. But Joe wants half of the booty, Willy 2 thirds of the remainder and Harry 3/4 of the still remaining booty.

Is Teddy's burglary worthwhile at all

How many coats does he have to steal at least, in order to keep one only for himself

MARK (no relation)
0.3 miles

PUMPS
4 hours

TEDDY
24

MARK (no relation)
0.3 miles
What a pity. He is a multi-millionaire.


PUMPS
4 hours

Pump A: 30 h/ V (V = volume of the water in the cellar), pump B: 20 h/ V, pump C: 15 h/ V, pump D: 10 h/ V. The pumping performances are expressed by reciprocal value formation into V/ h, then the deliveries of the pumps per hour can be added --> V/ 30 h + V/ 20 h + V/ 15 h + V/ 10 h = (after finding the common denominator considering the smallest multiple of the denominators = 60 h) --> 2V/ 60 h + 3V/ 60 h + 4V/ 60 h + 6V/ 60 h = 15V/ 60 h = (after reducing by 15) 1V/ 4 h (= 1/4 V/ h) --> (after reciprocal value formation): 4 h/ V , i. e. the 4 pumps had pumped out the cellar after 4 hours.


Mark:
TEDDY
24

One could set up a difficult equation with x = booty, in order to calculate, how much remains for the poor Teddy: (x - 1/2 x) - (x - 1/2 x) • 2/3 - ( (x - 1/2 x) - (x - 1/2 x) • 2/3) • 3/4 = ? (remains for Teddy). However, it works more simply, according to the idea: Teddy will get: x • 1/2 • 1/3 • 1/4 = 1/24 x. Of each stolen coat Teddy will get 1/24 (a twenty-fifth) as his remaining share. That is, in order to get one coat to keep for himself, he must steal 24 coats, a bad deal for him!


SOME CLASSIC RIDDLES:

1. Some months have thirty days and some months have thirty-one days. How many months have twenty-eight days

2. At the hardware store I was quoted 12 cents for one, 24 cents for 50, and 36 cents for 144. I wanted six. What was I buying and how much did it cost me

3. If two boys and a girl can beat their father in a tug-of-war, but their mother can win against a boy and two girls, who should win a contest between the father and a girl against the other and a boy

4. If a crab and a half weigh a pound and a half, but the half crab weights half as much again as the whole crab, what do half the whole crab and the whole of the half crab weigh

5. A chessboard has squares that are two inches by two inches by two inches. What is the diameter of the largest circle that can be drawn on the board in such a way that the circle's circumference is entirely on black squares

1-12 months

who should win a contest between the father and a girl against (((the other)))) and a boy ?
who is the other?

what is this?

WHAT AM I BUYING?
digits (like you use for your address)
The digit 6 costs 12 cents

CIRCE ON CHESS BOARD

ANSWERS FOR CLASSIC RIDDLES:


1. All twelve months have 28 days. Some have more as well.

2. Prices quoted were for house numbers at 12 cents per number. A number'6' cost me 12 cents.

3. The mother and boy. Pitting the 2 winning teams against the 2 losing teams (boy + boy + girl + mother versus father + boy + girl + girl) will obviously result in a win for boy + boy + girl + Mother over father + boy + girl + girl. Take a girl and boy away from each side, and boy + mother must still beat father + girl. PHEW!!!!

4. 2.1 pounds. The 'whole crab' must weigh 0.6 pounds, and the 'half crab' 0.9 pounds, totaling 1 1/2 pounds. If the former were halved and the latter doubled, the weights would then be 0.3 and 1.8 pounds, totaling 2.1 pounds.

5. The diameter is 6.324 inches. Diameter is equal to twice the radius.

And now for something completely different.

Theorem - Horses have an infinite number of legs!

Proof - A horse has an even number of legs.
It has Forelegs on the front.
It has two legs behind.

Six legs is an odd number of legs for a horse to have.
The only number that is both odd and even is infinity.
Therefore, horses have an infinite number of legs! QED


Three men go fishing on a camping trip. They collect all the fish they caught and put them in a cooler. They agree that when they leave they will divide the fish equally.

In the middle of the night, the first man gets sick and decides to leave. He opens up the cooler and counts the fish. He throws one fish away and then takes his third of the fish.

Later that night the second man has a family emergency and decides to leave. He opens up the cooler and counts the fish. He throws one fish away and then takes his third of the fish.

The third man gets up very early the next morning and decides to leave. He opens up the cooler and counts the fish. He throws one fish away and then takes his third of the fish. None of the men knows that the other men had taken any fish.

What is the smallest number of fish that would make this possible
