There is a 5 gallon and a 3 gallon box. You also have a hose with unlimited water. How are you gonna make the 5 gallon have 4 gallons using your items? (You do not know the exact measure measurements of a gallon)
you are given four different jars of 2 litres, 4 litres, 6 litres and 8 litres respectively with an unlimited water supply. Then you are asked to measure exactly 5 liters of water using them.
How will you do it?
Imagine you are in a cement box quickly filling up with water. The box is sealed on all sides, yet you still find a way out and survive. How?
