Fill in the 3L jug and pore the water in the 5L jug.
Again Fill the 3L jug and pore the water in 5L jug till the rim, Now you'll have 1L left in the 3L jug.
Empty the 5L jug and pore the 1L from 3L Jug to 5L.
Now again fill the 3L jug and pore that completely into 5L jug.
That will make a total of 4L in the 5L jug.

First take 5 lit of water in 5 lit can Then pour it to 3 lit can. After pouring 3 lit in the 3 lit can. 2 lit will remain in 5 lit can. Now empty the 3 lit can. And pour that remaining 2 lit water from 5 lit can into the empty 3 lit can. Now the 3 lit container can be filled with more 1 lit of water as it is filled with only 2 lit. Now again fill the 5 lit can and from that pour 1 lit to the 3 lit can. After pouring 1 lit the 3 lit can will be full. So, the remaining water in 5 lit container is 4 lit.

Answer: there are 2 ways as follows
Solution 1:
Fill the 5 liter jug. Then fill the 3 liter jug to the top with water from the 5 liter jug. Now you have 2 liters of water in the 5 liter jug. Dump out the 3 liter jug and pour what's in the 5 liter jug into the 3 liter jug. Then refill the 5 liter jug, and fill up the 3 liter jug to the top. Since there were already 2 liters of water in the 3 liter jug, 1 liter is removed from the 5 liter jug, leaving 4 liters of water in the 5 liter jug. Solution 2:
Fill the 3 liter jug and pour it into the 5 liter jug. Then refill the 3 liter jug and fill up the 5 liter jug to the top. Since there were already 3 liters of water in the 5 liter jug, 2 liters of water are removed from the 3 liter jug, leaving 1 liter of water in the 3 liter jug. Then dump out the 5 liter jug and pour what's in the 3 liter jug into the 5 liter jug. Refill the 3 liter jug and pour it into the 5 liter jug. Now you have 4 liters of water in the 5 liter jug.

A guy has two wires of varying thickness, which each burns in 60 minutes. He actually wants to measure 45 mins. How can he measure 45 mins using only these two wires. (he can’t cut the one wire in half because the wires are non-homogeneous and he can’t be sure how long it will burn).
