- Where has the last dollar gone? 2 answers
Two friends went to a store to buy a gift worth 50 dollars. The owner of the shop was not present so they bought the gift from his assistant and left. When the owner returned to the shop he told his assistant that the price of the item was not 50 dollars but 45 dollars. He asked his assistant to return 5 dollars to them. But the assistant kept 3 dollars to himself and gave the two friends 2 dollars. The friends divided the money among themselves. Thus they paid 24 dollars each. So they paid (24+24=)48 dollars it total. And the assistant stole 3 dollars. But (48+3)= 51 dollars. Where does the extra 1 dollar come from?
