This is a simple puzzle. Hope everyone has heard about this before.But you should be able to explain your answer. So try it.There are two empty buckets. One can hold 5 liters of water and the other can hold 3 liters of water. How can you collect 4 liters of water into the first bucket.Note: You have an unlimited supply of water and initially the buckets are empty.

We can do it in 6 stages. Let’s suppose that we have 3 buckets. I will write 3 numbers in every stage. The first number refers to the bucket that can hold 5 liters. The second number refers to the buckets that can hold 3 liters. And the third one refers to unlimited bucket.
Now we have: 5,3,0
Then we will have these stages:
i) 5,0,3
ii) 2,3,3
iii) 2,0,6
iv) 0,2,6
v) 5,2,1
vi) 4,3,1
