Logic puzzles

Here is an easy one..

You have a lighter and two fuses that take exactly one hour to burn, but they don't burn at a steady rate. For example, one fuse could take 59 minutes to burn the first inch and then burn the rest of the fuse in the last minute.

How would you use these two fuses to measure 45 minutes?

As this seems to be the thread for silly questions (other threads on DIYaudio seem to concentrate more on silly answers) can I ask a silly question: what is the point of this thread?

Hi,

Its only easy if you know the answer.

Light one fuse at both ends the other at one end.
When the first burns out light the other end of the other.

45 minutes.

rgds, sreten.

Find someone with a watch. Ask him, "If I give you these nice new fuses, will you alert me after 45 minutes has passed?"

 

[pinkmouse]

Give? Give!

Sell at a discount perhaps. Fuses are worth good money!

A twist on previous puzzle.


A man is traveling with a fox and two chickens, if he leaves the fox alone with the chickens the fox will eat the chickens. He comes to a river and needs to cross it, he finds a small boat that can carry only him and one animal, how does he get himself, the fox and two chickens across the river safely?

A rooster lays an egg at the very top of a slanted roof.

Which side of the roof will the egg roll off?

[Pano]

It will stay right on top with the rooster. Unlike hens, roosters lay square eggs

Fox and two chickens:

Start at side A
Take fox to side B
return to A empty
Pick up chicken#1, take to B, swap chicken for fox
Take fox back to A, swap for chicken#2
Take chicken#2 to B, drop off
Return empty, pick up fox, take to B

 

[Pano]

A man is traveling with a fox and two chickens

1. Fox across - leaves it.
2. Chicken 1 across, leaves it, returns with fox
3. Leaves fox, takes Chicken 2 across
4. returns empty
5. Brings fox across.

Then goes looking for egg laying rooster.

Oops! Was crossing the river while Cal was posting!

You have two buckets - one holds exactly 5 gallons and the other 3 gallons. How can you measure 4 gallons of water into the 5 gallon bucket?

You have infinite water and no markings on the buckets..
