Question

I have 3 jars,12 litre,7 litre and 5 litre. I have only 12 litre of water, can I have 2 X 6 litres of water?

Answer 1

Fill the 7 litre jar, put that in 5ltr jar and then you are left with 2 litre in the 7 litre jar. Transfer that 2 litre in the 12 litre jar. repeat the step 3 times. so now you have total of 6 litre in the 12 litre jar. and you are left with 6 litre which you can put in the 7 litre jar. So you get 2*6 litre of water.

Cheers :)

Answer 2

Fill the 5, poor it into the 7

Fill the five, poor into the 7 until full (you have 3 in the 5)

Poor the 5 (3) into the 12

Empty the 7 and repeat. The 12 now has 6 liters.

Now you can either keep the 6 liters in the 13 jar or the 7 jar...

and how to get the second 6.. hmmmm
