Answer 1

first, he will pour water to the 5L can ,then frm there to 3L can .....he will throw the water frm 3L can and pour the remaining water frm 5L can i.e. 2L.

now again he will fill the 5L can and then pour it to the 3L can....only 1L can be poured as it was already filled with 2L.....and then he will get 4L of water in the 5L can!!!
