Brain Teasers

Or.... a candle/lantern/lamp

Clever...

 

[ChipperT]

yep!

Anyone got the bucket teaser on the previous page?

Not to be a stickler but I think the teaser should be:

"Put me in your bucket and I will lighten your load, and a poorer man ye'll be."

This teaser is attributed to Benjamin Franklin.

Okay, I read over the entire Monty Hall Problem article. I still didn't buy it, so I broke out the playing cards. Now I get it. You guys were right, I was wrong. Hard to wrap the brain around it, but I finally get it.

While i'm at it... What can you put in a bucket, that you CAN see! that makes it lighter.

Two buddies were driving from their house to Sheffield, Karen drove the first 90km, and Dave took over the rest of the trip. On the way back, Karen drove first, and Dave took over for the last 100km. Who drove furthest?

Two buddies were driving from their house to Sheffield, Karen drove the first 90km, and Dave took over the rest of the trip. On the way back, Karen drove first, and Dave took over for the last 100km. Who drove furthest?

Dave drove furthest.

Karens Total journey = 90 + y km (y being what she drove on the way back)

Dave's Total Journey = x + 100 km (x being what he drove on the way there)

Therefore we can say the following:

90 + x = 100 + y

Therefore

x = y + 10

So karen drove:

90 + y

Dave Drove

100 + x

Substituting x gives

100 + y + 10

so he drove 110 + y

So dave drove 20km more than Karen

Another puzzle:

You are playing a game with an other person. There is a perfectly circular table, and an
unlimited supply of 10p pieces. You take it in turns to place a coin on the table, taking care that no coin overlaps another (touching is fine), and no coin can stick out over the edge of the table. The first person to break either of these rules loses. What strategy must you adopt in order to be guaranteed to win every time?

super glue?

I don't believe you.... I challenge you to prove it!

I accept your challenge.

"Brothers and sisters I have none" -Key piece of information.
"My fathers son" is the end of the sentance and is really just a wierd way of saying "myself" because we know his father had no other children, because of the first line.

So no we have.

"This man's father is me"

"This man's father is me"

Does that make sense?

"This man's father is my father's son."
Which would mean the man speaking is the father of the one in the picture.

Not

"This man is my father's son."
Which would make the man speaking the one in the picture.

Go first and use a table the size of a 10p coin.

Your first statement is correct.

I was simplifiying the original statement.

Brothers and sisters I have none, but this man's Father, is my Fathers son.

and as i said:
"My fathers son" is the end of the sentance and is really just a wierd way of saying "myself" because we know his father had no other children, because of the first line.

So no we have.

"This man's father is me"

Which would mean he is looking at a picture of his son.
Not sure where your second statement originated from.

Ah Ha! I see! Thank you for accepting my challenge.

The solution would work with a table of any size

I can explain that:
1. My son wanted to get up at 3:00 this morning
2. I'm still not fully awake
3. I misread your original answer

oh, well... Being that my body doesn't even recognize that there IS a 3 in the morning... I'll let that one slide. On a side note, you are making me really happy that I don't have kids, and really dreading the day I do.

Okay, my attempt at a puzzle.

There are three neighbours (Mr Jones, Mr Brown and Mr Smith) who live in three houses (see attached image).
Each wants to be connected to the gas supply, the water supply and the electrical supply. This is shown on the diagram as a simple line between a house and a supplier (Jones' water supply is used as an example).
The different utility companies all have the following rules in common - and here's where I hope I don't miss one out:
1. No two lines can cross (either from one supplier or multiple).
2. No line can split and supply two or more houses.
3. No line can pass through a house or another supplier on its way to its target.

How would you draw the lines on the diagram to ensure that each house receives a supply from all three suppliers?

It was certainly a lot different back when my only concern at that time was getting a cab home, but I wouldn't swap.

A ship anchored in a port has a ladder (beginning and ending with a tave), where the bottom tave touches water. The distance between taves is 20 cm and length of the ladder is 180 cm. Tide is raising water at 15 cm each hour. When will the water be on the third tave from the top?

Unless it already is, a large wave hits, or the cargo is increased to change the waterline, it will never be, since the ship will rise with the tide.
