You have two jugs. One has a capacity of five litres, the other three litres. Using only these two jugs as a means of measurement, how do you get exactly four litres into the five litre jug?

You fill the three litre jug and pour it into the five litre jug. you then fill the three litre jug again, and top up the 5 litre jug leaving you with one litre in the 3 litre jug. You empty the 5 litre jug and pour the one litre into it. You then pour another 3 litres into it to get 4 litres. Or if you prefer:
3l jug : 5l jug
3:0
0:3
3:3
1:5
1:0
0:1
3:1
0:4
= 4 litres

take the 3 litre jug and fill mark the jug
now fill the 5 litre and pour into the 3 litre down to your mark
make a mark on the 3 litre jug so you can now measure 2 litter's
measure 2 of these into your 5 litre jug that's 4 litres
well something like that

Use the three liter jug to fill the 5 liter jug. Fill it once, emptying the entire 3 liters into the five liter jug. There will be room left in the 5L jug for 2 more liters. Fill up the 3 L jug again and pour as much as you can into the 5 L jug, and then stop. You will have one liter left in the 3 liter jug.

Fill the 5 lt jug in full, pour its contents into the 3 lt jug. That would leave 2 lt in the 5 lt jug. Empty the 3 lt jug and transfer the 2 lt from the 5 lt jug into the 3 lt jug. The 3 lt jug would now have space for 1 more lt to fill it.
Fill the 5 lt jug again in full, and pour its contents into the other jug which will take just 1 more lt. The balance in the 5 lt jug would be 4 lt.

easy... fill 5 up and fill 3 up with it.. leaves you 2 . empty 3 and pour 2 that remain into 3. fill 5 up and fill 3 from it. It takes 1 to fill it to 3 and you are left with 4 in the 5 litre jug.

Easy. Just pour exactly four litres into the big jug. If you're having trouble guessing, just make sure there's exactly one litre left.
