Once upond a time there's a boy call Snow White and he lend 50 dollars from his father and another 50 dollars from his mother
And when he pass by a shop, he was attracted by a pair of sport shoes which was tagged 97 dollars, and he bought it
He was very happy with what he has, now he left only 3 dollars, he kept 1 dollars, and pay his father 1 dollars, and his mother 1 dollars also
afterall, when he add all sum together and he find that 1 dollars is missing so where is the 1 dollars, can you guys help him ?

Lol.. it is a rip off of Shankuntala Devi's famous problem...

3 people go to a restaurant... each pays 25 units of money.. The manager decides to give a discount and asks the waiter to give back 5 rupees. The waiter being like the OP ( ) keeps 2 units to himself and distributes 3 units among the 3 people equally . So each person gets back 1 unit.

Now each person paid (25-1) units that is 24 units. So... the manager catches on and recalculates.. 24*3 = 72 + 2 ( from the waiter)... = 74 .. where did 1 unit go?

the boy is wrong.

In you problem.. you must realize that there was no 1 dollar to begin with. You are getting confused by counting something that never existed.

The parents only paid the kid 98 $.. 49 each.  he paid 97 to the shop and kept one for himself.. the manner of your counting is flawed and if you read it a few times you will realize it.

These riddles are fun, but I think the one about the boy could be worded a bit better. At the end it should be stated that as the boy was thinking about he noticed that each parent gave 49, and he kept 1, so 49 + 49 + 1 =99. Because for the longest time I was thinking 97 + 1 + 1 + 1 = 100, so which one is missing?

Haha yeah, I understand it. I have come across several different versions of this. I just couldn't figure out how the first problem didn't add up for a while. Like how the second version (the one at a restaurant) shows the 'faulty' math at the end. I thought the boy one should too.
