Two boys, John and Peter, are running a 100 meter race. In the first race that they race John beats Peter by 5 meters. To make things fair, the next time they race John stands 5 meters behind the starting line.
If they run at the same speed as the first race who will win the second race?
John wins again. In the first race John ran 100 meters in the time that it took Peter to run 95 meters. So in the second race when Peter is at the 95 meter mark John will also be there (since 100-5=95). Since John is faster he will pass Peter in the last 5 meters of the race.

1,6,13,22,33, ?

A man goes into a barbershop and gets a $15 haircut. He pays the barber with a $20 bill, but the barber doesn't have change because it is an especially slow day. The barber goes to the flower shop next to his own and trades the $20 bill for a $10 bill and two $5 bills. Then he gives the man his $5 in change.
Later the lady from the flower shop confronts the barber and tells him that the $20 bill he gave her was counterfeit. The barber agrees and he gives the lady a different $20 bill.
Later that day he tries to figure out how much money he lost. What did he lose?
He lost $5. The lady from the flower shop gave him $20 in change, but eventually got $20 back. She broke even. The man who got the haircut gave the barber nothing (except counterfeit money) but got $5 back from the barber. So the barber lost only $5, and gave a free haircut.
