1. First fill 5 liter jug.
2. Pour from 5 liter jug to 3 liter jug. Now 5 liter jug will have 2 liters. 3 liter jug will have 3 liters.
3. Pour the water in 3 liter jug back into well. Now 3 liter jug is empty. 5 liter jug will have same 2 liters.
3. Pour remaining 2 liters from 5 liter jug into 3 liter jug. Now 3 liter jug will have 2 liters. 5 liter jug is empty.

first fill the five litter jug.. pour its content to three litre jug.. now the water remaining in five litre jug is two...
empty the three litre jug and again fill it with the remaining content of five litre jug....
now fill the five litre jug... pour water from five litre jug to three litre jug which already contains two litres of water... thus it can accomodate only one more litre... therefore the five litre jug will now contain (5-1) 4 liltres of water

simply you can see this in following way
step 1- use half of the 3 litre jug content
in this way you will use 1.5 content
step 2-use half of the 5 litre jug content
NOW
total content used=content used in step(1) + content used in step(2)
=1.5 + 2.5
= 4 litre content

3)Pour the 3 liter jug's water back to well and empty the 5 liter jug water into 3 liter jug. Now the 3 liter jug will have 2 liters of water and 5 liter jug is empty.
