Help with simple math problem .

One day , a customer came to Helen’s shoe shop to buy shoes, the costing of this pair of shoes is $15 ,the price is $21, the customer handed $50 over to Helen ,but Helen do not have the change ,so she changed $50 from her neighbour ,then gave $29 change to the customer. but soon, her neighbour discovered that $50 is counterfeit money, however Helen should return $50 to her neighbour .

The question is super simple : How much did Helen lose ?

44 would be an obvious answer, but I am sure the actual answer will be something dodgy =)

$50. If a worthless $50 has come into the equation then the total loss is $50. If Helen reimbursed the neighbour $50, then the entire loss is Helen’s, right? Helen loses $50.

The customer gains $50. $29 change in real-money and a $21 pair of shoes.

If $6 of the shoe’s price is profit, then $44 makes sense. But if you regard the $6 not as profit which comes out of thin air, but actual payment for hours spent making the shoe / running the shop then Helen has actually lost this too.

I love math … not really

The answer of all questions: 42

she gives over the real $50 and so she loses $50 but she also gave away the shoes and the change to the customer which were equal to $50 so does that not make the loss $100?

I just finished high school with informatics-mathematics, intensiv informatics profile and i don’t have a clue for the answer…how cool this can be?

Yes,I hate math.

double post..sorry… i need to change my internet provider..small speed

$44 plus the expected profit of $6.
Also, one neighbour. And one customer, even with false money.

Other option. As she owns the false $50. She goes to any Apple store and buy any stupid ithing for that price. Total lost: $0.
