think again over the puzzle.

[Sigid]

Gee, I got one right! Shaping up to be a good day...

Here's a pretty old one:

A woman goes to Home Depot to buy something for her house. When she asks the price, the clerk tells her, "Well, one costs 25 cents, fourty four costs 50 cents, and two hundred costs 75 cents".

What is the woman buying?

[Sigid]

eurekamind:

How about this? The girl and the boy were different ages because they were fraternal twins, not identical?

[~*Nat*~]

-{ Quote: "not yet! I said...there is a logical answer to this puzzle.

Shooty...I thought I had the perfect answer...but I think Sigid got it right ! :D

[eurekamind]

-{ Quote: "eurekamind:

Sigid....They are identical twins of the same age and they celebrate their actual birthday. There is no 'choice or wish' involved for celebration as ~*Nat*~ thought.

Think more.....think extra-ordinary !!!

Damn good answer Texcritter and it is relevant!:)

But this is the answer I was looking for-

If you add all the numbers from 100 to 1 the sum total is 5050.

A bit of trivia-
There is a well known story about Karl Friedrich Gauss when he was in
elementary school. His teacher got mad at the class and told them to
add the numbers 1 to 100 and give him the answer by the end of the
class. About 30 seconds later Gauss gave him the answer.

The other kids were adding the numbers like this:

1 + 2 + 3 + . . . . + 99 + 100 = ?

But Gauss rearranged the numbers to add them like this:

(1 + 100) + (2 + 99) + (3 + 98 ) + . . . . + (50 + 51) = ?

If you notice every pair of numbers adds up to 101. There are 50
pairs of numbers, so the answer is 50x101 = 5050. Of course Gauss
came up with the answer about 20 times faster than the other kids.

[Franklin]

FINISHED FILES ARE THE RESULT OF YEARS OF SCIENTIFIC STUDY COMBINED WITH THE EXPERIENCE OF YEARS.

Now count aloud the F's in that sentence. Count them ONLY ONCE; do not go back and count them again.

How many did you count?

[WSFuser]

Puzzle: Four men A,B,C and D want to cross a bridge. The bridge is of a width such that a maximum of 2 people may cross at a time.

'A' takes 10 minutes to cross
'B' takes 5 minutes to cross
'C' takes 2 minutes to cross and
'D' takes 1 minute to cross.

conditions to follow:
If two people cross the bridge together, they must walk at the pace of the slower one. So if A and B cross together, they will take 10 minutes. Also, it is night. Each trip requires a flashlight. There is only one flashlight. The men are not allowed to toss the light over the river. They must pass it hand to hand.

How fast [in minutes] can you make them cross the bridge?

Puzzle: The wise teacher offered the three noisiest students a deal. He showed them that he had 2 RED hats and 3 BLUE hats.

The deal worked like this:

The three students would close their eyes, and while their eyes were closed, the teacher would put a hat on each of their heads (and hide the other two hats).

Then, one at a time, the students would open their eyes, look at the other two students' heads, and try to guess which color hat was on their own head.

Any students that guessed correctly would have no homework to do the rest of the semester. But any student that guessed wrong would not only have to do their own homework, but also have to help on everyone else's homework.

The students drew numbers to see who would guess first. Then they closed their eyes and the wise teacher put a hat on each one's head.

Jimmy, who was to go first, opened his eyes, looked at the others' heads, and said he didn't really want to play. He couldn't tell for sure and he didn't want to guess in case he was wrong.

Next, Merry opened her eyes and looked at the others' heads. She also thought about the fact that Jimmy had said he couldn't tell. Then she said she didn't want to risk it either. She couldn't tell for sure.

Melissa was third. She just stood there with her eyes still closed tightly and a big grin on her face. "I know what color hat I have on," she said.

And she gave the right answer.

Your problem is to figure out what color hat Melissa had on and how she knew for sure.

Remember: Melissa didn't even look!

The students drew numbers to see who would guess first. Then they closed their eyes and the wise teacher put a hat on each one's head.

Jimmy, who was to go first, opened his eyes, looked at the others' heads, and said he didn't really want to play. He couldn't tell for sure and he didn't want to guess in case he was wrong.

Next, Merry opened her eyes and looked at the others' heads. She also thought about the fact that Arturo had said he couldn't tell. Then she said she didn't want to risk it either. She couldn't tell for sure.

Melissa was third. She just stood there with her eyes still closed tightly and a big grin on her face. "I know what color hat I have on," she said.

And she gave the right answer.

Your problem is to figure out what color hat Melissa had on and how she knew for sure.

Remember: Melissa didn't even look!

I know the answer to this one
I've seen it before but it had a different story to it
(prisoners and black and white buttons) and I can tell you the answer
can be difficult to understand.
clue : you really have to scrutinise what the others see.

'A' takes 10 minutes to cross

A & B go across = 10 mins.
B go`s back with flashlight. = 5 mins.
B & C go across = 5 mins.
C go`s back with flashlight = 2 mins.
C & D go across = 2 mins.

10+5+5+2+2=24 :D

Then again, if D cross`s with C it may knock it down to 23.....I think.

nineteen

do we have to explain the answer? if so, here it goes:

C and D cross. 2 min
D goes back. 1 min
A and B cross. 10 min
C goes back. 2 min
C and D cross. 2 min

My observation is that if we remove the first letter from each word [ except 'evive', which should be 'Revive' because there is no word like 'evive'] then each word would have the same spelling either ascending or descending.

These are the 4 grandchildren and with jack and rita = 6 children
The two mothers are Ann and Rita
The two fathers are John and Jack
The 3 sons are Jack and his 2 sons
The 3 daughters are Ann and her 2 daughters
John is the father in law of Rita
Ann is the mother in law of Jack
Rita is the daughter in law of John

as an addition Jack is the son in law of Ann

OK,I think I have it now.

Flipping to the right or left puts the word upside down and back to front.

Write "CHIDE" on a bit of clear plastic and flip it backwards upside down.

Spells the same ,isn't back to front and is upside down!.

upside-down means: imagine you are standing at the top of the letter. Now, read the letter from there looking down, front side.

[Franklin]

Upside down to me means to stand something on its head.

New List of letters that can stand on their head and still look the same.

B C D E H I K O X-any more?

upside-down, they would look like this.

ya ... It will look the same because you are looking backside from the top.

It seems you do not read carefully ... I told you to look front side always.
Side will never change in upside-down condition.

This is what is meant by upside down
write SWIMS in the top left hand corner of a page
turn the page round so that it is now in the bottom right hand corner and it still reads SWIMS

But doesn't the first S become the last S doing it that way,hence it is back to front!

You have turned the letters back to front and upside down!

Leave the letters in order and put them on their head without rolling them left or right.

In other words roll them on their heads backward or forwards.

This is getting technical but I'll stick to my guns and claim that SWIMS is wrong and has been wrong for a long time as I have recalled seeing the puzzle quite a while ago.

Bridge crossing .... look at WSFUSER post 131 and it shows how to do it in 17 minutes

[eurekamind]

Puzzle :

A Proof That 2 = 1:

1. X = Y let x=y
2. X*X = XY multiply by x on both sides
3. X*X - Y*Y = XY - Y*Y subtract y*y from both sides
4. (X+Y)(X-Y) = Y(X-Y) factorise
5. (X+Y) = Y divide by (x-y) on both sides
6. Y+Y = Y replace x with y
7. 2Y = Y factorise
8. 2 = 1 divide by y on both sides

Where lies the flaw in the logic?

[Sigid]

Dividing by zero always yields interesting results...see step 5

[Texcritter]

as sigid states in step 5 divide by (x-y) on both sides
as x-y = 0
it is not logical to divide by 0 as anythng divided by 0 will always = 0
