A doctor in Michigan has a sister who lives in California but the sister does not have any brother that lives in Michigan, how come??
:P

It is same even if the different coin is lighter than others, isn't it?

* got it right after I posted that... anyway, ahile tatkalai ta aru chhaina... yeso kam pani ganu paro ni :)

yes pretty, its same if you know one is lighter, but problem is if you don't know if it is lighter or heavier, just different... then it's not the same...you'll have to go one more step, I think

but I was trying to solve if we don't know if the coin is heavy or light...... we know only that it is different ........ i was trying to tackle that problem ...... if you understand my soln you can do that in 3 steps ........ if no can you do that in 3 steps ... we don't know if its heavy or light

It says a doctor in Michigan, doesnot mean he needs to live in Michigan. He might be living in a close-by state, and still fits the criteria of the question.
But Can I Have The Address Of the Sister? So that I can scre* her, and end my virginity.

its more challenging than the original one please try and don't look at my previous soln ...... you will understand what i meant by interchange if you solve

Damn, I am a nerd here now, I thought nobody answered the question, but it was solved just in the second thread, which was hidden in my window. DAMN it.

its good to check how logical u are if u r comp science major

yeah, ritthe, I agree... more challenging, but I have already seen your soln :), and I think that's the answer...!

hetterika and preeti did u try the einstein one it will kill ur time easily

Back to the 60 L container question.
--------------
Slackdemic's solution:

1. Pour the mixture from the original container (60 L) to 7 L container and transfer that 7 L to 43 L container. Repeat it.

At this point, the 43 L container has 14 L of oil.

2. Now, the trickiest part: Pour the oil from the original container to 11 L container. And, pour the 11 L container, which is full, to 7 L container. Now the 11 L container has 4 L oil (11-7=4).

3.Pour that 4 L water to the 43 L container where there is already 14 L of oil. Now it is altogether 18 L of oil in 43 L container.

4. Repeat step #2 three more times, which will result in 12 L of oil (4*3=12)!!! So altogether 18 + 12 = 30 L of oil in 43 L Container. And, at the same time 30 L of water is left in the original 60 L container.
-------------------

I thought you had got it right at first glance. But then I got suspicious because your solution has no need for the 43 L container. I couldn't figure out where the flaw was in your solution for a while, but I do now.

You cannot repeat steps 2 & 3 three times as you have suggested.

Let's say you did it one more time and added 4 L of oil to the 43 L container. Now you have 22 L of oil there. You pour the 7L of oil back into the original container, which now has 30L water and 8L oil.

What next? When you repeat step 2 again, you have 8 L of oil and 3 L of water in the 11 L container. When you pour that into the 7L container.. you have 1 L of oil and 3L of water left - NOT 4 L of oil.

Still trying to work out the solution.

Ritthe, haven't tried Einstein one- this one is enough for now... back to work time :(,

will try later

republican that has laready been solved my juggy i think ....... try other one posted few threads above and the one if einstien

I think I've worked it out! But I still don't understand why the 43L container is there, could there be a shorter/better solution?

Basically I've used a combination of 7s and 11s that add up to 30 :

11 + 11 + 11 + 11 - 7 - 7 = 30

So

1. Pour from 60L to 11L and then to 43L container - you have 11 liters oil in the 43L container now.

2. Pour from 60L to 11L and then to 43L container again - now you have 22 liters oil in the 43L container.

3. Now pour from 43L to 7L to 60L container - you have 15 liters oil in the 43L container.

4. Again, pour from 43L to 7L to 60L container - you have 8 liters of oil in the 43L container.


That means you have 22 liters of oil in the 60L container now. Repeat step 1 twice (pour 11 liters twice into the 43L container) and you have 30L oil in the 43L container.

ritthe, juggy's solution used a non-existent "bottom" of the container :) I tried to solve it without assuming that.

wuts up azn, long time no see.....

sadbut true i need the answers from you...for the math test..

Here's one:

You have two containers of the same size - one is filled with milk and the other is filled with the exact same amount of water. Let's say Container A has milk and Container B has water.

You take one cup of milk from Container A and mix it in Container B.

Then you take one cup of the milk/water mixture in Container B and mix it in Container A.

Considering that milk and water is evenly distributed when mixed, does Container A have more water or does Container B have more milk?

.hehe Republican!! I agree to disagree with my solution, But It seems Paradox has already solved that one up there!! I tried to elaborate his solution though!!
But it is good to see you using your brain too!! Brain damage it is!!
and republican can u be more clearer!! The Container A has milk and Container B has water. But were they completely full??...:S..:S
Have a good one everyone!!..:)

Republican,

Container A water=Container B milk

right??
