- Where has the last dollar gone? 2 answers
The owner of a ration store sells sugar sacks weighing 50Kg for \$50, but he gives a special discount to his neighbors, and sells it to them for \$45.
One day the owner, whose name is Jack, left the store and left his employee Jony in charge. Two of his neighbors, Tom and Jane, bought a sack of sugar together and spent \$50, each of them paying \$25.
Unfortunately, Jony sold the sack to them without knowing that they are his boss's neighbors.
When Jack came back to the store, he saw that Jony made a mistake, so he sent him to pay Tom and Jane a \$5 discount.
Jony stole \$2 from the 5\$ and gave \$1.50 each to Tom and Jane, giving them a total of \$3. So now Tom and Jane have paid \$25 - \$1.50 = \$23.50.
Each one paid 23.50\$, so both Tom and Jane paid \$23.50 + \$23.50 = \$47 together.
Jony stole \$2, so the total is \$47 + \$2 = \$49
Where is the missing \$1?
