Two Buckets Water Problem
We have two buckets, 1 of capacity 3liter and another of 5 litter. We have 5 litters of water. So how will we make combinations such that 1 bucket will have exactly 4 litters of water?
First pour 5 liter of water in 3 liter container
now you will have 2 liter remaining in 5 liter
now empty the 3 liter and fill it with 2 liter from the 5 lit container
now take 5 liter and pour one more liter to 3 liter container
now you are left with 4 liter in 5 liter container
