here's another one?

Question

i went with my friend keira to buy a chair from ayman for 30 dollars i payed 15 and she payed 15 .
later the owner of the shop got back and asked ayman if he sold anything he told him about the chair he sold us the owner told him that he has mistaken the price is 25$ and not 30$ so he gave him 5 bucks to return ayman took 2$ and gave me 1.5$ and keira1.5$,
so that made me payed 13.5$ and keira also,
13.5 + 13.5 = 27
27 + 2 (that ayman took them) =29
but we payed 30$
where's the that dollar?
can anyone tell me ?

Answer 1

You didn't actually pay $30, you (and Keira) paid $27. This is because Ayman gave you back $3 total ($1.50 each to you and Keira).
Of that $27, the owner got $25, and Ayman got $2.

Answer 2

Its a misdirection.

They paid $12.5 each for the chair
They paid (albeit unknowingly) $1 to the ayman.

This adds to $13.5 which is what they effectively paid.

Adding what they both paid is $27 and that gives $3 left... which is returned to them as $1.5 each.

Thus the $2 was already in that $27 and the misdirection.

Answer 3

At first cost of chairs=25/2=12.5
after taking 2$,
cost=(25+2)/2=13.5
then both you had to give 13.5$
then total cost=13.5x2=27$
The owner gave you and her 1.5$ each.
then the total is =27+(1.5X2)=30$.
This type of sums are called fallacy

Answer 4

The 27 includes the extra dollar.

Answer 5

This riddle is one of the oldest chestnuts in mathematical puzzles, and has shown up numerous times in this forum. Another responder has provided a correct analysis, and I need not duplicate that.

Answer 6

The easiest question on questions and answers. Piece of cake!!!!! therefore, I decline to answer. Will be kind of humilating to my intellect. thanks.
