This can be easily solved starting from the third guy since no egg is left after he took the half of the egg. Third guy: Second guy: First guy:

by putting all conditions except "Large and small are different by 4" as letters below should be these numbers. so we can conclude that First condition: Second condition: and Last condition: In ...

How about another one last one

I wrote a program to solve all possible conditions including everything. The code is running for some days now and I have found lots of close results. According to the benchmark, it will take a couple ...

Here is the optimal answer with Shown as knights;

Here is lateral thinking answer: then Here is the actual answer: How did I find?

This is the original drawn of this question: You will easily notice that AFE angle is 20. And AFE and FCA triangles are isosceles triangle: Moreover, if you draw a line through point E as 20 degrees ...

4.8179 km I have made a little improvement on @squeamish ossifrage answer where it just requires a little optimization on it, resulting; with the minimization of the equation. First of all, using ...

First of all, by a simple geometry principle: $\triangle CED$ and $\triangle AED$ have the same base $|ED|$ and the area ratio between $\triangle CEF$ and $\triangle CFD$ has to be the same as the ...

Here is the answer: More is coming! Here is our original diagram completed with for sure later; the length $|DE|$ is our $x$ and let's put some specific angle that we are going to work with in our ...

One can even find $2017$ by using only 5 numbers given in the question without changing the order as below: Here are the actual answers for the question:

Here is the most probable optimal solution with some extra modification of previous answers: The score is 1.3348. Here is the brute Force Code written by @fireflame241 confirming this is actually ...

Here is my result for $1,4,6,7$ from $1$ to $53$. $1^{4-6-7}=1$ $1^4-6+7=2$ $(1-4)/(6-7)=3$ $1+4+6-7=4$ $1-4/(6-7)=5$ $1+4-6+7=6$ $(1^{4})^{6}*7=7$ $1^{4-6}+7=8$ ...

Here is my attempt, and it is probably optimum if I didn't miss something: It is the idea is simply; In other words,

because,

It has to be (mathematically) This is our boat and geometry of it. First of all we know that $x-y=1$ since the Little Johhny pulled 1 yard the boat and he is 1 meter above from the sea level. $b^... View answer Accepted answer 11 votes Here is the answer: This was pretty easy though. View answer Accepted answer 11 votes Pretty simple to be honest, or So the answer will be; View answer Accepted answer 11 votes Let's call our glasses$1,2,3$and$4$. We are trying to find out which glass is poisoned, so we don't need the poisoned water! Initially we have 4 glass of waters as shown below; Pour$1$away and ... View answer 10 votes Here is my answer: as here the order is as below View answer Accepted answer 10 votes Here is the answer:$2=23=35=2+37=\frac{43-3}{2}-1311=43-2\cdot(13+3)13=1317=43-13\cdot219=13+3\cdot223=43-2\cdot(13-3)29=43-...

Originally there are; 10 S, 6 V and 5C For the first case where he wants to have 7 S, 5 V and , 4 C. (so we dont want to have 3S, 1V and 1C) In the worst case scenario; so I do not want to ...

This is not a proof but basic intuition; The value of $d$ should be (considering they are wise and choose not random points but the best possible point where they have the advantage) where it makes ...

Here is the answer: The reason is And The rest is

The player has to pick at least $6$ cards whatever number on the card is at the beginning since the sum of biggest numbers does not exceed $124$ until $6$ cards are picked. If the player picks $4$ or ...
The answer is I have used simple matrix multiplication while solving the problem; Let say who said 1 is A, 2 is B, 3 is C, 4 is B ... J said 10; $\frac{J+B}{2}=1 \ for \ A$ an so on; \begin{...
