First fill the 7ltr pot and transfer water to the 5ltr pot. now 7ltr pot has 2ltr water. spill the water of 5ltr pot and fill it with water of 7ltr pot. now 5ltr pot has 2ltr water. again fill 7ltr pot and transfer water to the 5ltr pot. now 7ltr pot has (7-(5-2))=4ltr water. spill the water of 5ltr pot and fill it with water of 7ltr pot. now 5ltr pot has 4ltr water. again fill the 7ltr pot and transfer water to the 5ltr pot. you got it. 6ltr water in the 7ltr pot (7-(5-4))=6ltr.

Fill the 7 and pour it into the 5 leaving 2 left over in the 7.

Pour the 2 into the pan and repeat 2 more times and you'll have 6 in the pan

1) Fill the 7 litre pot

2) Pour the 7 litre pot into the 5 litre pot

3) Empty the 5 litre pot

4) Pour the 7l pot into the 5l pot

At this point, the 5litre pot has 2 litres of water in it. The 7l is empty.

5) Refill the 7l pot, and use it to fill the 5l pot.

Because the 5l pot had 2l of water in it, it was only able to take 3 more litres. The 5 litre pot is full, and the 7l pot has 4 litres in it.

6) Now empty the 5l pot, and fill it with the 4l from the 7.

7) Fill the 7 again, and you will be able to pour exactly 1 litre into the 5l pot before it fills, leaving you with 6 litres in the 7l pot.

If we cannot fill the pan by pouring water 2 times, both hahahahaha and soop got the answer.

[Guest]

another answer is-

Fill the 5LT pot and pour it into the 7LT pot. Fill the 5LT pot again and fill the 7LT pot. This would leave you 3Lt in the 5LT pot. Empty the 7LT pot and pour the 3LT from the 5LT pot into the 7LT pot. Fill the 5LT pot again and fill the 7LT pot. This would take 4Lt leaving you 1LT in the 5Lt pot. Empty the 7LT pot and pour the 1LT into it. File the 5Lt pot and pour into the 7LT pot and you have 6LT.

Fill the 7Ltr pot first and pour it to 5 ltr , and empty the 5 ltr one. Pour the 2L in the 7Ltr pot to the 5Ltr pot. Fill the 7Ltr again and por it to 5Ltr one and empty the 5Ltr pot. Now you will be having 4 Ltr in 5Ltr pot.Fill 7 Ltr again and pour it to 5Ltr pot to make it full. Now you have 6Lt in your 7Ltr pot

hey guys use spoilers please.

1) fill 7L pot

2) pour 7L pot into 5L pot until full

3) dump 5L pot

4) pour remainder into 5L pot

repeat

repeat steps 1,2 again (3rd time).

at end 7L pot will have 6L of water

end of cycle 1 state: 7L - 0L, 5L - 2L

end of cycle 2 state: 7L - 0L, 5L - 4L

end of cycle 3 state: 7L - 6L, 5L - 5L

Well the easiest way to do it with the least amount of transfers really makes much more sense. Ok, heres what you do.

1) Fill 5 Lt pot and then pour it into 7 Lt pot. This will leave you with an empty 5 Lt pot and an almost full 7 Lt. pot.

2) Fill 5 Lt pot once again and pour into 7 Lt. pot that was almost full. This will leave you with 3 Lt. in your 5 Lt. pot.

3) Pour the 5 Lt. pot that now contains 3 Lts. into the pan.

4) Repeat steps 1-3 again and it will have 6 Lts in the pan and your door will open. FREEDOM!!!

If you filled the 7ltr pot half way and the 5 ltr pot half way then dump the water from the 5 ltr pot into the 7 ltr pot you would have it!

3.5 ltr + 2.5 ltr =6 ltr

I will type the amount in each pot after pouring/filling. The number to the left will be the amount of water in the 7 liter pot (pot A) , and the number on the right will be the amount of water in the 5 liter pot (pot B) .

fill -- 7 0

pour from A to B -- 2 5

dump A -- 0 5

pour from B to A -- 5 0

fill B -- 5 5

pour from B to A -- 7 3

dump A -- 0 3

pour from B to A -- 3 0

fill B -- 3 5

pour from B to A -- 7 1

dump A -- 0 1

pour from B to A -- 1 0

fill B - 1 5

pour from B to A -- 6 0

The pot with the capacity of 7 liters now has 6 liters of water.
