Solution

Information provided:

  • We have 4 jars of water.
  • Size  of jars = 2 L, 4 L, 6 L, and 8 L.
  • Water supply is unlimited.

 

 

Step 1:

We have 4 jars, of different size.

First we need to fill the 4-Liter jar completely.

Now, empty it in the 6-Liter jar. Now, 4 liter jar is empty and6 Liter jar is filled upto 4 liter.

Fill the 4 liter jar again. after that now we have 4 liter water in both the jars i.e., 4 liters and 6 liters respectively.

Step 2:

Now take both the 4 liter and 6 liter jar, and pour both of them into 2 liter empty jar at same rate.

Now, as we are emptying both the jar at same rate, so now the 2 liter jar will be filled completely, and the 4 liter and 6 liter jar will be now containing 3 liters each.

Step 3:

Now use any 4 liter or 6 liter jar which have 3 liters of water and use 2 liter jar filled with water and empty it in 8 liter jar.

Now the 8 liter jar have the 5 liters of water in it.
