Remove 6 liters of oil from a large oil container using only two mugs of 9 liter and 4 liter respectively.
i) Fill the 9 liter mug and pour oil from it into the 4 liter mug to fill it. Now, oil left in the 9 liter mug is 9-4=5liter.
ii) Empty the 4 liter mug and again pour oil from the 9 liter mug to fill the 4 liter mug. Now oil left in the 9 liter mug is 1 liter.
iii) Empty the 4 liter mug again and pour the remaining 1 liter of oil from the 9 liter mug to it. Now, the 4 liter mug contains 1 liter of oil and the 9 liter mug is empty.
iv) Fill the 9 liter mug again and fill the 4 liter mug using it.
Space left in the 4 liter mug is 3 liter hence the 9 liter mug now contains 6 liter of oil.
