Question

I have a question of my own and i think its impossible Please Help

There were 3 students, 10 dollars each. They put their money together to buy a 30 dollar watch. when they leave the store, the shopkeeper remembers that the watch was worth 25 dollars, not 30.
So he gives his trainee 5$ to return to the students. The trainee keeps 2$ for himself and gives 3$ to the students. That makes 1$ returned to each one.

So now every student has in fact paid 9 dollars. 9*3=27 with the 2 dollars of the trainee 27+2=29
1$ is missing.

Answer 1

I know i help alot of you but i think this is impossible;

Answer 2

Any of you know?

Answer 3

no money is missing


they effectively paid $9 each and contributed 9*3 = 27 dollars total


the item costs $25, so they paid $2 more than they had to, which is why the trainee has the $2

Answer 4

Are u sure because; I need 100% on this test.

Answer 5

basically when you add 27 and 2 to get 29, you're making the fallacy of adding the total amount paid to the total amount left over...the two don't mix

if anything, it should be 27 + (-2) and not 27 + 2

Answer 6

Answer 7

sure just one more though
