The Sunday Afternoon Puzzle!

[lspencer534]

This puzzle was prepared by Mensa Barbie, so try to out-smart that little tart! Grab a beer, and no Googling!

1. This is a very simple puzzle. However, experiments have shown that only 4% of people get the answer right. Imagine that you are presented with the four cards represented in the illustration below. Each card has a number on one side and a letter on the other.

You are told that every card that has a vowel on one side has an even number on its opposite side. Which card or cards must you turn over in order to ascertain whether or not that statement is true? (Since whatever answer you give could be considered guessing, please explain your answer.)

2. There is a certain clock in my house that is not wired into anything. In fact, it runs on a battery, and it reads correctly all the time without my having to change it every spring and fall at the time changes.

The question is, how does it do this?

3. A barber had his first customer of the day, who happened to be a friend. When he was done, the barber refused to take the money from the customer. The fellow said, "Look, I know we're friends, but business is business. I want to pay for my haircut."

The barber said, "Here's what we'll do: You open the cash register. I don't have any idea how much money is in there. But, you match whatever is in there, and then take out 20 bucks."

The customer says, "Okay," and he does that.

The barber says, "Gee, I kind of like this." So, the next customer comes in, he gets his haircut, and the barber says, "You can do the same thing my first customer did. Open the cash register, match what's in there, and then take out 20 bucks."

The second customer does that, and he leaves. The third customer does the same. The fourth customer, after receiving his haircut, opens the cash register, and says, "I can't do it. "

The barber says, "Why not?"

"There's no money in here. Not a cent."

The question is, how much money was in there to start?

4. A man leaves home for a mountain at 1 pm and reaches the top at 3 pm. The following day he departs from the top at 1 pm and gets home at 3 pm, by following the same path as the day before. Was he necessarily ever at the same point on the path at the same time on both days?

5. Use the letters given to complete the square so that three other words can be read downwards and across.
What are the words?

# 2. There can be at least two answers. The first is that it receives a signal from the US Naval Observatory master clock. The second, as it is with my cell phone, it receives a signal from the telephone company digital master clock. Although is varies over time, in order to operate correctly, the entire telephone network MUST be synchronized. Otherwise, frequencies would drift and the network would cease to work.

This clock doesn't need to receive a signal to be correct.

This clock doesn't need to receive a signal to be correct.

Then all it has is one hand and only shows the minute, not the hour.

If it has both hands, hour and minute, it has to be reset occasionally, there is no clock that is 100% accurate, regardless of whether it is electronic or mechanical. Even the atomic clock has to have a leap second added occasionally

It has only one hand, but it's the hour hand. What is it?

4 . No ..:D

[SnowDale]

#4 Yes. Think of it as a graph of position vs. time. There is no way to draw the second curve without intersecting the first curve.

1. 2 cards (A and D). Card A to verify it has an even number on other side. Card D to verify that it doesn't have a vowel on the other side. You don't care about card B (doesn't matter what it has on other side) or card C (don't care either since statement says all cards with vowel have even number on other side, not that all cards with even number have vowels).

[lspencer534]

4 . No ..:D

Sorry I didn't make the instructions clear. Please explain your answer.

[pappytinker]

It has only one hand, but it's the hour hand. What is it?

It can't be a day clock because depending whether it was initially set to standard time or daylight time it would be pointing to the wrong day for one hour part of the year.

[SnowDale]

#2 How about if you live in Arizona or one of those other places that doesn't follow Daylight Savings Time?

[lspencer534]

#4 Yes. Think of it as a graph of position vs. time. There is no way to draw the second curve without intersecting the first curve.

Correct. In other words, an easy way to visualize this is to imagine, instead of one man making one trip and then making the return trip, two men making the trip at the same time. One man leaves the bottom at 1pm and heads toward the top. The other leaves the top at 1pm and heads toward the bottom. Regardless of their rate of travel over the course of the trip, they must pass each other on their respective journeys.

You don't care about card B (doesn't matter what it has on other side) or card C (don't care either since statement says all cards with vowel have even number on other side, not that all cards with even number have vowels).

Correct. Most people think the answer is card A and card C. However, the correct answer is that you need to check card A and card D.

Whether there is a vowel or a consonant on the other side of card C makes no difference. The statement "every card with a vowel on one side has a consonant on its opposite side" can only be shown to be false if there is an odd number on the opposite site of card A and/or a vowel on the opposite side of card D.

In his book Finding Moonshine Professor Marcus Du Sautoy offers the following explanation for why most people get the answer to this puzzle wrong: "Our brains are so desperate for symmetry that they also check whether every card with an even number on one side has a vowel on the other. So the brain directs you to pick up card C. ... It seems that our subconscious works according to some sort of symmetrical logic. It thinks that if the statement 'if A then B' is true, then so is its converse, the mirror image, 'If B then A'. In general, this is far from true. Logical deduction is usually very unsymmetrical."

Not a day clock

Here's a hint: You wouldn't need this clock in Arizona.

[CuzzinJack]

Similar to SnowDale's answer --- graph with position height /time ..Say the first trip up was a straight line then the return trip could be curved above or below that line and only meet at each end ..or something like that ...:shots:

i`m here for the pics, aint smart enough to figure the puzzles out. :cert:

4. No. the traveler will probably take the same amount of time going from home to the base of the mountain as going from the base of the mountain to home but it will take longer going up the mountain than it does for him to come down therefore being at a different location at a given point in the time span.

#2 How about a Tide clock?

#2 How about a Tide clock?

That's it!

http://i702.photobucket.com/albums/ww22/lspencer534/Tide_clock.jpg

It's a tide clock, an analog clock that has only one hand, the hour hand. It runs slower than a normal clock because the tides don't come at six-hour intervals. High tides are anywhere from 12 hours and two minutes apart to 12 hours and 50 minutes apart. And you certainly don't have to change it when they change all the other clocks.

The Arizona clue did it for me. My trouble was that this land lubber had too much conflicting time information. Is the 48 minute variation built into the timing mechanism or is it just set on an average.

A tide clock is a specially designed clock that keeps track of the Moon's apparent motion around the Earth. Along many coastlines the Moon contributes the major part (67 percent) of the combined lunar and solar tides.

Tides have an inherent lead or lag, known as the lunitidal interval, that is different at every location, so tidal clocks are set for the time when the local lunar high tide occurs. This is often complicated because the lead or lag varies during the course of the lunar month, as the lunar and solar tides fall into and out of synchronization.

The lunar tide and solar tide are synchronized (ebb and flow at the same time) near the full moon and the new moon. The two tides are unsynchronized near the first and last quarter moon (or "half moon"). The best time to set the clock is at the new moon or the full moon, which is also when the clock can most reliably indicate the actual combined tide. Along shorelines where both components are important, a simple tide clock will always be least reliable near the quarter moon.

2) It's magic :lol:

It's gets a signal from the atomic clock or it's tied into grenich(sp) mean time

BRB, checking out answers :leaving:
