Can I calculate this puzzle saying 9 x3 .. ? why ??

Question

Hi there.. today when i was with my friend someone give us a puzzle but there was something i couldn't understand about it i hope you can explain it for me, he said : " 3 guys paid a 30$ thats 10$ for each to buy 1 radio from a kid then when the kids boss came back he asked the kid for much he sold the radio he replyed for 30$ the boss said its worth only 25$ and he order him to give them the 5$ back, the kid take 2 $ and give each one 1$, now if we calculate the money 3 guys paid 30 10 from each 10 + 10 + 10 = 10 x 3 = 30, and for the radio if we tell it was for 25 $ the kid take 2$ + 3$ for each also thats 30 $ but if we tell each of the guys paid whats like 9$ and 9 x 3 = 27 + 2$ with the kid thats 29 and there appear to be 1$ missing how is that happening ?? why cant i calculate this way ??

where can i find more puzzle like this ??


thanks for passing by ;)

Answer 1

that is a good question, im not sure how to answer that but all i can say that if the boy had sold it for $25 then each guy wold have paid about $8 and some cents but since they paid $10 each that is $30. ha gave them back the 3 dollars that means that he actually took $27 for the radio ,so $27+$3 that he gave back is $30. Did this help ne bit?

Answer 2

This is a common puzzle and easily thought out. Going back from $30 gives the wrong answer.

The radio is $25, the boy got $2 and each customer got $1...total $30.

Answer 3

9x3 =27 -2 = 25 cost to store
the $2 is to be subtracted from the 27 not added.
10x3 =30 originally paid
1*3 = 3 amount refund to the 3 guys
2 amount stolen by the clerk
30-3-2=25 amount paid to store

Answer 4

You can't because they actually only paid $25, not $30, so you take the $27 and subtract $2, not add it. 27 - 2 - 25

Try a search for math puzzles

Answer 5

Of course you can't solve it by giving back $1 + $1 + $1 + $2.

That will mean you are dividing the rest of the $5 into 4 people & not 3 people.

The $2 should actually be divided among 3 people & not given to 1 small boy

Get it? :)

Answer 6

you have have been given me, i will think of of something that could in good shape with each and every clue, yet no longer something that suits a subject working by each and every of the clues, in certainty, i do no longer even see an common subject.

Answer 7

LOOK AT IT THIS WAY...
$30.00 MINUS THE $2.00 THAT THE DUDE KEPT = $28.00
