The False Coin

Shadow Gaunt
​Writer, Ravenclaw

A boy was walking alongside a marketplace and saw a stall with toys. He walks up to the stall owner and asks for the toy soldier that costs 10 rallod. The boy gives a 25 rallod bill to the stall owner. However, the owner doesn't have change so he asks his neighbor for change. His neighbor gives the stall owner two 10 rallod and one 5 rallod. The stall owner gives the boy the toy and 15 rallods. Suddenly, the stall owner's neighbor yells to him that the 25 rallods he gave her were fake. The stall owner was forced to give his neighbor the money back. How much rallods did the stall keeper lose?
