You have two buckets one with capacity of 5 Liters and the other with a capacity of 3 Liters. You have to measure 4 Liters using the two buckets.How will you do it??

Well the solution is simple. First fill the 5 L bucket completely and empty the water in the 3L bucket. Now empty the 3L bucket and pour the remaining 2L water left in the 5L bucket in 3L bucket. Now fill the 5 L bucket and pour it in the 3L bucket till it is full. You will have 4L water left in the bucket.
