unless your really gd at estimating or the bowl has marks on it (where u cud just fill the 9 litre up to 6.) i wud do this.

Filll the four litre and pour it into the 9 litre

half fill the four litre and pour it into the 9 litre.

Use (5) 4 liter containers and (1) 9 liter container.

Fill up the 9 liter container with water

Fill (2) of the 4 liter containers with the water from the 9 liter containers.

Pour the remaining one liter into the 3rd 4 liter container

The 9 liter container will now be empty.

Refill the 9 liter container with water

Fill the last (2) of the 4 liter containers with the water from the refilled 9 liter container.

Pour the remaining one liter into the 3rd 4 liter container ( You will now have 2 liters in the 3rd 4 liter container)

Again the 9 liter container will be empty.

Pour one of the 4 liter containers and the 2 liters from the 3rd 4 liter container into the 9 liter container.

You will now have 6 liters in the 9 liter container.

Nothing hits the floor.

Ok yu fill the 9 liter bottle up all the way then pour it into the 4 litter bottle leaving 5 litters in the 9 liter bottle. Then you dump out the 4liter bottle and dump the 9 liter bottle into the 4 liter bottle leaving 1 liter in the 9 litter bottle. Then once again you empty the 4 liter bottle. Then you pour the remaining 1 liter out of the 9 litter bottle into the 4 liter bottle. ok? now you fill the 9 liter bottle up again and dump it into the 4 liter bottle which now contains 1 litter of water so to fill it you would haev to dump 3 liters of water leaving 6 liters in the 9 liter bottle.

It is unclear as to whether or not you have unlimited water to use and whether or not water can be "measured" onto the floor (which is still measuring)

Assumign you can't do these things.

Maybe specifiy more clearly that you are only supposed to use 1 9- litre bowl and 1 4- litre bowl, because the problem just said "9- litre and 4- litre bowls"

Otherwise, there is another solution: Fill 2 9-litre bowls. (Total is now 18). Take out 4 litres from both bowls using the 4-litre bowl. Then empty those bowls. Now, take another 4 litres out of one of the bowls. Now you have one bowl with 5 litres, and the other with 1. Pour 1 into 5. Now you have 6 litres.

Not sure if anyone thought of this but ever consider filling up 2, 9 liter bowls(18l) to the brim. Then grab 4, 4 liter bowls(16l) fill them you will have 1 liter left in either bowl add them together then dump the contents of one of the 4 liter bowls into the 9 liter with 2 lites already in it. 6 liters.

1. Fill the 9 liter bowl.

2. Pour 4 liters into 4 liter bowl (leaving 5 liters in the 9 liter bowl).

3. Empty the 4 liter bowl.

4. Pour 4 more liters into the 4 liter bowl (leaving 1 liter in the 9 liter bowl).

5. Empty the 4 liter bowl.

6. Pour the last liter from the 9 liter bowl into the 4 liter bowl (leaves 1 liter in the 4 liter bowl and 0 in the 9 liter bowl).

7. Fill the 9 liter bowl.

8. Pour 3 liters from the 9 liter bowl into the 4 liter bowl (this will fill the 4 liter bowl which has 3 liters empty space and leaves 6 liters in the 9 liter bowl).

9 You now have 4 liters in the 4 liter bowl and 6 liters in the 9 liter bowl.

2. Pour 4 liters into 4 liter bowl (leaving 5 liters in the 9 liter bowl).

3. Empty the 4 liter bowl.

4. Pour 4 more liters into the 4 liter bowl (leaving 1 liter in the 9 liter bowl).

5. Empty the 4 liter bowl.

6. Pour the last liter from the 9 liter bowl into the 4 liter bowl (leaves 1 liter in the 4 liter bowl and 0 in the 9 liter bowl).

7. Fill the 9 liter bowl.

8. Pour 3 liters from the 9 liter bowl into the 4 liter bowl (this will fill the 4 liter bowl which has 3 liters empty space and leaves 6 liters in the 9 liter bowl).

9 You now have 4 liters in the 4 liter bowl and 6 liters in the 9 liter bowl.

I got:

Assume: A=4 size bowl and B=9 size bowl

Resolve: Arrive at 6

Fill B, leave A empty

A=0, B=9

Pour 4 from B in to A

A=4, B=5

Dump A

A=0, B=5

Pour 4 from B in to A

A=4, B=1

Dump A

A=0, B=1

Pour 1 from B in to A

A=1, B=0

Fill B

A=1, B=9

Pour 3 from B in to A

A=4, B=6

...now can I drink?

just fill the 4 letre bowl and pour it into the 9 letre bowl then half fill the 4 letre bowl and pour that into the 9 letre bowl which will make 6....

Fill the 4L bowl only one liter at a time and pour into 9L bowl. Repeat until 6L is achieved. Is it me or is this not actually a brain teaser but rather a test on basic measuring skills?
