A little puzzle...

[El Jefe]

Something to think about...

...any bright spark got the answer?

:)

[mikeyj]

Hola,

Did you buy it from a hole shop?

Eddy Buddy:rolleyes:

Line A-B is distorted (curved) to make the first triangle of slightly less area than the second triangle.
Line D-E is straight.

Therefore the triangles appear of similar dimensions but the change in the hypotenuse line makes that one square difference.

& the winner is....

.....knowall..!!

& the prize is...

now you've got to post one. ;)

[sabio]

A snail is at the bottom of a 20 metre well.
Each day he manages to climb 4 metres, but at night he slides down on the wet surface 3 metres. If he starts on 30th June, what date will he be out of the well?

[carbine]

19th July.

[sabio]

Sorry, not 19th July

[Alboxgal4]

Was cheered up by the ugly fruit and veg, now my brain hurts trying to work that last one out. Thanks guys!! LOL x

[mikeyj]

Hola knowall,

Is it Tuesday??

Justin Case:p

[DieSse]

16th July

Next!

16th July

Next!

Correct.:cool:

[El Jefe]

Well done DieSse..!

Feel free to have a shot at setting the next puzzle.

[DieSse]

A hunter sets off from his camp, and walks 3 km due south. He shoots a bear. Then walks 3km due east, and seeing nothing else to shoot, goes back to camp. Altogether he covers 9 km.

What colour was the bear?

[The Sheriff]

White ? his camp was at the North Pole.

[DieSse]

Well reasoned Fred - your turn now.

I couldn't get this one. I got stuck on the triangle (3km south, then east, then back = 9km). At first I thought it's something to do with magnetic declination at the poles, but well, may not..??

It's because of the walking along a close line of latitude close to the pole you are walking in a curve, if it was plotted on a flat piece of paper.
So whilst walking East, you are actually turning left a little at the same time.
Not well explained but that is it.
A bit like walking down one side of a cone then walking around the bottom a bit then up to the top.
Is that better or worse now?:)

[DieSse]

To put it simply - there's only one place in the world your camp could possibly be if you go 3km south then 3km east and it's only 3km back to where you started - and that's the north magnetic pole.

Mind you - to be totally pedantic - I'm not sure whether polar bears roam within 3km of the north pole - but that's not the import of the puzzle!

[carbine]

Though I understand what is being said about the travelling 3 K's south, 3 K's east the 3 K's back again I don't understand the concept that it has to be the north pole except they start off by going south, though it doesn't say where from however, the only place you can ONLY go south from in any direction is the north pole and I think this is the real answer to where you are and that I can accept, but the theories about curvature of the earth and walking down and round a cone I think are just red herrings. At the end of the day you just walk what in basic schoolboy geometry is known as an equilateral triangle, a triangle with 3 equal sides. That can done in the Gobi Desert or Yellowstone park just as easily. Yellowstone is also a home to the Brown Bear!

Any chance Sherriff is going to continue the sequence?

Sorry carbine, but you are wrong.
Equilateral triangles have angles of 60º in their corners, remember!

Try it at the Equator:
3 miles south, 3 miles east you will be the square root of 18 miles from where you started. That is about 4.25 miles.
This question is really good for understanding the 3 dimensional aspect of curved objects.
Have fun figuring it out!

[El Jefe]

Here we go with a new brain teaser...

Which shape from the bottom line fits on the end of the top line, and why?

[mikeyj]

Hola,

I believe it's A.......one segment moves successively to the right by one whilst the other segment moves successively by two to the left.

I thank you.

A Askey.:p

[El Jefe]

WoW..!

Well done mikeyj.

Correcto...

Feel free to set the next one...

[mikeyj]

Hola,

OK then...

In your pocket you have 7.38 euros.

It is made up of four different coin denominations and the largest is 1 euros.

There is exactly the same number of each coin.

How many of each coin is there and what are their values?

Answers on a postcard please!

Ben Dover.:rolleyes:

[carbine]

How about 4 Denominations, 6 coins of each denomination?

6 x 1E = 6.00

6 x 20c = 1.20

6 x 2c = 0.12

6 x 1c = 0.06

Total = 7.38

Hola,

Spot on Carbine, muy beans, now it's your turn......

Huw Janus:eek:

[carbine]

I have three wine jugs. Jug A holds 8 litres and is full. Jug B holds 5 litres and is empty. Jug C holds 3 litres and is also empty.

I want to measure out 4 litres. You are NOT allowed to throw any of the wine away. How do I do it?

[sabio]

Put 3 litres from A into C then empty C into B.
Put 3 more litres in C, this leave 2 in A.
Fill B from C, leaving one litre in C.
Note the position of the wine at 1 litre before emptying into A.
A now contains 3 litres.
Pour wine from B up to the mark in C that you have remembered, then pour it into A.
A now contains 4 litres, so does B.

Sounds complicated doesn't it?
The other option is go and buy Jug D which contains 4 litres;)

[carbine]

Logic, that's all. Your turn.

[sabio]

A man lives on the tenth floor of a building. Every morning he takes the elevator down to the lobby and leaves the building. In the evening, he gets into the elevator, and, if there is someone else in the elevator - or if it was raining that day - he goes back to his floor directly. Otherwise, he goes to the seventh floor and walks up three flights of stairs to his apartment. Can you explain why it is so?

[The Sheriff]

He is a Dwarf { Sorry not allowed to say that } he is vertically challenged ?

in the morning he can reach the button for the Ground Floor as it is the bottom one - Going back to 10 in the evening he cannot reach the button - unless it it raining and he has his umbrella !

[sabio]

Your turn Fred!
