Mathematical Query (Simple)

This might be simple for you guys/gals. But I'm just had a few beers and it's not working out so simple.

If I enjoyed a meal, and the price of the meal was EUR65, and my companion paid EUR60, and I paid EUR5 - but I later wanted to make sure my companion only had to pay 50% of the costs, how much should I later give to that person to repay them?

1. 32.50?
2. 30.00?
3. 27.50?

And why?

Creamy Goodness

well the meal cost 65 euros
of which you should pay half

>> 32.50

you have paid 5.

>> 32.50 - 5.00 = 27.50

that is the way i did it and got the same answer so 27.50 it is

Thank you kindly folks, I am somewhat less under the affluence of incohol now and can see you are spot on.

I really don't see the point of this thread...

Jaysus, this is primary school stuff.You must have been hammered!;)

wrafter

Yes, I was. Completely.

And Dragon Master - you may not have seen the point of the thread, but I think you responding to it 24 days after the thread has effectively come to a close will equally match any pointlessness you saw in the initial posting.

You are lost in a forest. The forest is between two villages. In villageA live only liars, they always lie. In village B people always tell the truth. You want to go to village B. Then you see a man from village A or B. You can ask him only one question.
Which question will you ask him to know for sure where village B is ?

try and get that!

"If I ask you does this path go to Village A would you say no".

Both liars and truthtellers will give the same answer and tell you if it is the right path or not.

Dragon Master

Do you know whether the person is from village A or B?

Diarmsquid

"Which direction is the village where you come from?"

The man from village A would lie and point to village B.
Village B man would aslo point to Village B.
