I asked this problem long time back when I was young.

Oh really? Actually I heard this problem from my friend.

You are given 8 balls. One of the balls is heavier than the rest which are all the same weight. It is impossible to determine the heavier ball by the shape, size or lifting it up. You are given a 2-plated beam balance. Using the balance twice, how can you determine which ball is heavier.

Why are so many advertisers joining the forum nowadays and getting banned due to advertising there own math websites?

There is a way. Don't want to advertise it (no pun intended )

Please can we let this thread fade away so it doesn't give anything away. Thanks.

A better option is to close this topic.

Do they include e-mail address also?

Hi, how to find the root of the following function by fixed point iteration method ?

-exp(1/(3*exp(t)))/(3*exp(t))

AFAIT, its this function:

Where did you get 0.571143115080177 from?

See the graph which Ganesh posted. You will see that it converges down to X-axis and almost touches it at that value.

Belated Happy New Year 2018!

You are in this forum for almost 8.5 yrs!

When was the forum updated?

Hi, you can see these 2 links which may be very helpful for you...

Hi alter ego,

You need to post a diagram for this as well as the other thread. I think you missed it.

Its easy.

Don't you think it should be in *Help Me*.

And is that xyz = 1 rather than abc = 1 ?

Bob

Yeah it is.

I solved it but it took 2 whole pages to solve it. Phew! I finally got the numerator and denominator as equal and hence it is equal to 1.

I'm sorry I gave the question wrong, I edited it . Now see.

Yeah, I forgot that.

Oh wow,

It seems ages since Ganesh has posted something in *Help Me*. He usually used to post in *Ganeh's Puzzles* and *Dark Discussions at Cafe Infinity*.

If a cone and a cylinder have the same radius and height, you'd expect the volume of the cone to be less than the cylinder. But why one third and not some other fraction, or maybe even an amount unconnected with the cylinder's volume?

I can show this if you know some calculus; specifically a little bit of integration. Post back if you want to see this.

Yeah, I too want to know about it.

a + d = 4

b + c = 6

How did you get these 2 equations?

After 15 min of thinking I found this but I don't know whether its correct or not...

iamaditya, it has been four and a half months since your last reply to bobbym, who has since died.

Yeah I know, (and I was the first few of them to know about it) so I was not expecting a reply. I wanted other members to give answers but till now I haven't received a single one.

The answer to # 15 is log(12).

Yes it's correct.
