1)You have two buckets – one holds exactly 5 litters and the other 3 litters
How can you measure out 4 litters of water into the 5 litters gallon bucket ?
(Assume that you have an unlimited supply of water and that there are no measurement markings of any kind on the buckets.)
2) Can you connect these nine dots with just 4 straight lines?
Hint :you have to think outside the box!
