The ball
Three friends go to buy a ball, and it costs 300 CZK. Everyone gives 100 CZK. Later, the seller finds out that the ball costs 250 CZK. He will send 50 CZK after the apprentice. The apprentice buys a snack for CZK 20. The shop will return 30 CZK to the boys - 10 CZK each. Each boy paid 90 CZK for a ball. 3*90=270+20 for a snack - that's 290 CZK. Where's the damn 10 CZK?
