Here it is - the ultimate test of your mathematics skills!!!
How it works
- I will post a maths question daily
- Members will try and solve it giving their working and answers
- I will post the answer the next day OR someone gets the correct answer & working OR after 4 people have tried to work the question (whichever comes first), if I am offline, then the new question will be posted the next day.
- There are no 'rewards' or 'prizes' but its just for fun and learning some maths along the way too
Rules:
1 - Use of calculators is strictly prohibited! (you can cheat and use one, but remember if you cant be fair even alone then how can you expect to be fair to others?)
2 - ALL working MUST be shown, this is not just about getting the right answer, but its also to see if the person knows how to work the problem and most importantly others can learn how to solve problems using the examples of solved questions.
27-7 =20
20/2 =10
10+7=17 women; and if you are doing algebra you will be able to work out that there will be no peace for the minority of men working there.
and here is one for you if you are not too busy studying;
A farmer dies and leaves his sheep to be divided between his two sons, the sons don’t want the sheep and sell them.
However many sheep there are in the flock is the same as, how much money they got for each sheep.
The big brother divides the money and ends up with one more ten pound note than his little brother, so he gives his brother the pound coins from the sale.
The little brother said that is not fair you have more than me, so big brother makes a cheque out for the difference, so how much is the cheque for?

Lol man this dosent seem like a maths problem to me at all
10 sheep
10 pounds per sheep
Thus 10 x 10 = 100 pounds
100/2 = 50 pounds each
Now if the brother had 10 more pounds that his little brother he would have 60
so the check for the difference would be 10 pounds
However you also said "so he gives his brother the pound coins from the sale."
Assuming that instead of a 10 pound note he gave his prother 10 pound coins
Then in that case the cheque would be of 0 pounds since they would have equal money already.
If you think logically a hundred pounds is ten X ten pound notes, so they would both have exactly the same £50 each, and the big brother would not have to write a cheque for the difference.
If it helps you have come up with the wrong number of sheep; this is not a trick question, but it requires you to do a bit more thinking.
I don't think you should spend too much time on this if you have your exams shortly, maybe I should give you a clue to put you out of your misery.
the number you are looking for must give you an odd number of ten pound notes when multiplied together, and you do not have to think of a big number/
This dosent seem like a maths problem
There are only four things you can do in maths, add, subtract, divide and multiply; the sheep problem needs you to do three of those things to solve it so it must be maths.
There must be better things to do to pass the time; :rant:

3 Sheep
Each sold for 10 pounds.
Total 30 Pounds.
Big bro gets 20 pounds
Lil bro gets 10 pounds
Big bro gives lil bro 5 pound cheque.
But what dosent make any sence is this statement "so he gives his brother the pound coins from the sale"
Does that imply that he gives his brother 5 pounds in coins?
Because if so then no Cheque is necessary.
If not then the Cheque would be 5 Pounds
Furthermore what the question does not specify is if the money was divided equally or not "The big brother divides the money and ends up with one more ten pound note than his little brother"
So for all we know the money was divided unevenly.
The reason I am trying not to assume anything is because the exam I am about to give (GMATS) warns heavily against assumptions.
There is a question format on it called "data sufficiency" which tests a person ability to be able to judge if the question is solvable based on the given data or not.
I will be kind to you because you really should be spending time studying.

If you looked a little closer at the last part of the question,

The little brother said that is not fair you have more than me, so big brother makes a cheque out for the difference, so how much is the cheque for?
The little brother wants the money shared out fairly, so would it be safe to assume that he wants the same as big brother?
You need to find a number when multiplied by itself gives you an odd number of tens.
6x6=36
big brother takes two ten pound notes =£20
little brother takes ten pound plus the six pound coins =£16
you might be tempted to say the cheque is for £4, but in fact it is for half that so they both end up with £18,
The problem was solvable as it was, but it requires you to do a lot of thinking, once you worked out the numbers the calculations were very simple.
If you multiply numbers by themselves you might find that the ones giving an odd number of tens end in six.
It must have been some strange and weird person thinking up this little test originally.
I am off to church followed by a twenty hour shift at work, so no more questions for a while
I pray that you will gain from your exams, take care
