A little maths problem for you

**Driveway** · 05-23-2002

The answer is Dell. I'll show you:

Code:

Embark, Cotton, Orche, Calm, Small, Duvet, Frost

Watch:

The non-capital non-ascending letters (an example of ascending letters : tlkbdf) form words.  E(m)b(ar)k, C(o)tt(on)  (maroon)
O(c)h(re), C(a)l(m) (cream)
S(ma)ll, D(uve)t  (mauve)
F(ros)t, D(e)ll  (rose)

whoo, that was hard, wasn't it?

Oh, would you look at that, 8 pages, answer to match stick please

I wonder if we have to think in 3D to solve the matchsticks problem . . .

Could've sworn I did a similar problem before.

**Jet_Master** · 05-23-2002

ok. here is the match stick problem answer:

Code:

             ____
            |    | 
            |____|____
                 |    | 
                 |____|____
                      |    |
                      |____|

i hope you get it. the four long sticks are used to form two "+" signs. then the four short sticks are used to complete both squares.

There are three people in front of you. You know that:

One of them is God. He knows everything, and always tells the truth.
One of them is the Devil. He also knows everything, but lies.
The third person knows nothing, but answers questions as if he knows the answers. His answers, however, are completely useless and could be right or wrong.

You can ask a total of three questions that can correctly be answered with yes or no, each to one of the persons. You may choose whom to ask.

Determine who is who...

Determine who is who...

lemme try, i am not sure i am right, but here goes:

- Ask the first person an obvious and universal question (example: Are you asleep?)
- If he answers yes, he is the devil. if he answers no, go to next step:
- Ask the second person the same question.
- If he answers yes, he is the devil. if he answers no, go to next step:
- If both people answered no, that means that the last one is the devil.

--- now we know who the devil is.
-ask the devil which one out of the other two is the god.
- the one he points to is not the god. that is the person who knows nothing.

So the person left is the god.

---------------------------------------------------------------------------
that might not be the answer you are looking for, but i think that works... is that correct?

But isn't 'ar' in Embark ascending and so is 'uv' in Duvet?

**dbaryl** · 05-24-2002

I think you're almost there, but...

- Ask the first person an obvious and universal question (example: Are you asleep?)
- If he answers yes, he is the devil.

This could be the reguar person as well, he could be lying... I think.

Oh, also, the Devil does not know everything

A glass has the shape of a cone upside down:

\ /
|

The diameter at the top of the glass is 6cm, the height of the "cone" is 8cm. The ones who manufacture the glass wants it to fill 10% more liquid. How do you measure the glass to accomplish this?

A cone has a circle at the bottom. You probably already know the formula for calculating the area of a circle. The formula for calculating the volume of the whole cone is: base area (circle) multiplied with the height, divided by 3.

Think of it this way....

if a letter ascends, it goes past an imaginary half-way point. The only ascending non-capital letters are-
l, k, t, f, b, d (sometimes the j ascends, depends what font you are using)

I am not sure i understand. Are you asking for a way to fill the cone 1/10 with water? If so, are you allowed to use anything besides the glass itself?

Code:

#define G God
#define D Devil
#define I Idiot

bool question = "Person 1, Is the Idiot immediately left of the Devil?";
char order[3] = "XXX";

if (question)
{
	question = "Person 2, are you the Idiot?";
	if (question)
	{
		question = "Person 2, is Person 3 God?";
		if (question)
		{
			order = "GDI";
		} else {
			order = "IDG";
		}
	} else {

		question = "Person 2, Is Person 3 the Devil?";
		if (question)
		{
			order = "IGD";
		} else {
			order = "DGI";
		}
	}
			
} else {
 
	question = "Person 3, Are you the Idiot?";
	if (question)
	{
		question = "Person 3, Is Person 2 God?";
		if (question)
		{
			order = "GID";
		} else {
			order = "IGD";
		}
	} else {

		question = "Person 3, Is Person 2 the Devil?";
		if (question)
		{
			order = "IDG";
		} else {
			order = "DIG";
		}
	}
}

I don't know if i'm answering the wrong question or not, but for the glass question posted Zewu, i got this,

increase the the height by 0.6

or

increase the diameter by [{sqrt(396) / sqrt(10)} - 6]

again i don't even know if i'm answering the right question...

**Jet_Master** · 05-24-2002

The diameter at the top of the glass is 6cm, the height of the "cone" is 8cm. The ones who manufacture the glass wants it to fill 10% more liquid. How do you measure the glass to accomplish this?

so the manufaturer wants the new volume of the glass to be 10% of the glass more than the current volume of the glass?
so, if the current volume of the glass is x,
the manufacturer wants the new volume to be:
x + 10%(x)

is that correct? i need to know that in order to answer the question.
