I've got a fun little maths problem you might want to get your head around... and chances are you probably already know about the puzzle. Welp!
A long time ago lived a very rich trader in the desert who had three sons. The rich trader had a whopping seventeen camels. The trader decided that after his death, his oldest son should inherit half of his camels, the middle one would get a third and the youngest son received a ninth of the seventeen camels.
Your task is to calculate how you're going to divide the camels among the three sons, and tell me how you got there. It'd be very helpful if you didn't have to cut up some of the camels..- vizIIsto

Yes.In post 97, Mitillos wrote:1/2 + 1/3 + 1/9 = 17/18
But it's not the answer I want to hear. How will you divide the camels among the sons?- vizIIsto

That still doesn't answer the question how you will divide the seventeen camels among the three sons. Give a complete answer with reasoning.In post 99, Mitillos wrote:Lend the dead man a camel.- vizIIsto

And that's exactly how to solve the problem.In post 101, Mitillos wrote:Since you insist: You can't. By the time the will takes effect, the trader is dead. It is impossible to change the number of camels, assuming you have provided all pertinent information, thus at least one camel will have to be chopped up.
If we allow silly solutions like lending a dead man a camel, he now has 18 camels, which can be divided as you have requested. The sum I gave shows that one camel will be left over, which can then be returned to the lender.
1/2 of 18 is 9; 1/3 of 18 is 6; 1/9 of 18 is 2. 9 + 6 + 2 = 17. You don't need to 'lend a camel' to solve it, but adding an extra camel is how you will be able to divide the 17 camels fair and square.- vizIIsto

I forgot that this thread existed. I made a maths geeks thread in GD (by the way, check it out!) and posted a problem there which I'm sure fits in perfectly well here. Here's the problem:
This question appeared on an exam. It went as follows:
"The product of the three integers x, y and z is 192.
z = 4, and p is equal to the average of x and y.
What is the minimum value of p?"
The four answers were: a) 6 b) 7 c) 8 d) 9,5
But... No one gave the right answer.
What is the right answer?
To make it a little bit easier in case you struggle to find the right answer, here's three hints. But don't read them unless you really need some help, and one by one!
