Measure exactly 2 liters of water if you have:

1. 4 and 5-liter glass

2. 4 and 3-liter glass

1^{st} Fill the 5-litre bowl, pour water from it to fill the 4-litre bowl, which you empty afterwards. pour the remaining 1 litre to the 4-litre bowl. Refill the 5-litre bowl and pour water from it to fill the 4-litre bowl (where there is already 1 litre). Thus you are left with 2 litres in the 5-litre bowl.

2^{nd} The same principle - this time from the other end. Fill the 3-litre bowl and pour all of the water to the 4-litre bowl. Refill the 3-litre bowl and fill the 4-litre bowl to the top. And there you have 2 litres in the 3-litre bowl.
