a 15 gallon aquarium contain 60 litters of 3% salt water solution. If everyday, 500ml of plain water was evaporated, How many days is needed to have 5% saltwater solution?
---------------------
3% of 60 liters = 1.8 liters of salt
If 1.8 liter is 5%, total is 1.8/0.05 = 36 liters
60 - 36 = 24 liters evaporated.
24/0.5 = 48 days
