    Hi I need help with this please.

    I want to get a top for €25 so I borrow €12.50 each from Alan and Laura. I go to the shop and the top now costs €22 so with my €3 change I give Alan and Laura €1 each and keep €1 for myself so now I owe Alan €11.50 and Laura €11.50. €11.50*2=€23 so €25-€23=€2 where does the extra € come from?

    I know that this is wrong somewhere I know it's in the way it's said but where. I there any mathamatical way to prove this 'cause I ned it to be fool proof cause i know that when I explain it all I will get is them repeating the riddle again and again.

    it cost €25 in the beginning you got half from each that 2*€12.50
    it got reduced to €22 = 2*€11
    plus the €3 change = 2*€1.50

    €11+€1.50 = €12.50

    Top = 22 euro, + the euro you took = 23 euro. other 2 euro goes to Alan and Laura, the problem lies in the fact that the wrong numbers are used to make up the 2 euro, because it doesn't matter that they gave you 25 euro. Should be 11.50x2 =23 -22 = 1 which you have. :rolleyes:
