  • Last Updated : 29 Nov, 2020

There are two jugs each of 4 and 3 liters respectively , without any measuring marks. how many minimum steps are required to have 2 liters of water into the 4 litre jug (the jugs can be filled any number of times with water, and they can be emptied any number of times). 


Note that this puzzle is different from the one discussed here. Here we need 2 litre water in 4 litre jug (not in any of the two jugs). 


Answer: 6
Step 1 : Fill 3-litre jug with water completely 
Step 2 : Empty water from 3-litre jug into 4-litre 
Step 3 : Again, fill 3-litre jug with water completely 
Step 4 : And pour water from 3-litre jug into 4-litre jug until 4-litre jug becomes full 
Step 5 : Empty the 4-litre jug. Now, we are left with 2 litre water in 3-litre jug and 4-litre jug is empty.  
Step 6: Transfer water of 3-litre jug to 4-litre jug, resulting in 2 litre water in 4-litre jug.
