    I’ve thought about this and I cant figure it out…am I being thick?

    3 men in café, have food, bill comes to £30 so they give waiter £10 each.
    Apparently waiter got bill wrong - it should have been £25. So manager gives him £5 to take back to men.
    He decides to pocket £2 and give them each £1 back (because they won't know).

    How much therefore did each man pay? (£9 surely….£10 - £1 back?)
    3 x 9 = 27
    Plus £2 in waiter’s pocket = £29!

    Where did other £1 go?

    Edit: appalling grammar!

    If this is a two-part question then the first part is easy. 😵

    As for the secnd part, there is no missing pound.

    You are wrongly assuming that 27 + 2 should equal 30.
    $27 has been paid out.
    The cafe has $25 and the waiter has $2.
    End of story.

    Let the 3 men pay 3x
    Let the overcharge be y
    Let y be of the form 3n + k where k is the amount that the waiter keeps
    The waiter gives back 3n to the men so that they have now paid 3x - 3n in total
    The problem says that 3x - 3n + k should equal 3x
    This is only true when k = 3n
    But in your problem k = 2 and 3n = 3

    Well for one thing the men paid a total of 27 /30 paid 3 returned/
    (the bill was 25 and the waiter kept 2 so 25+2 = 27)
    Now to look at it the other way around each paid 9 or 27 paid total,minus 2 taken by the waiter equals 25 = the bill.
    So there is really nothing missing.
