If you had an infinite supply of water and a 5 quart and 3 quart pail how would you measure exactly 4 quarts?

Answer 1

1)Fill the 3 quart pail to the top first

2)transfer the water into the 5 quart pail, which leaves you with 2 quarts to fill.

3)Again fill the 3 quart pail and transfer the water into the 5 quart which leaves you with 1 quart left in the 3 quart pail.

4)Throw away the water from the 5 quart pail and pour the 1 quart into 5 quart pail.

5)Again fill the 3 quart pail to the top and pour the water into the 5 quart pail leaving you with 4 quarts of water.

Answer 2

Place both buckets side by side. Mark 3 quart marker on both, 5 quart one will be 2 quart more place the 3 quart pail on the marker of 5 quart, since now it will be 6 quart, you will see that 1 quart measurement. track it and then fill the

5 quart bucket with 4 quart water in 1 try!

Below is the Previous answer by Stephen!

We're going to do this in steps:

1. Pour 3 Qts into the 5 Qt bucket.
2. Fill your 3 QT bucket again, and fill the 5 QT bucket up to the top.
3. You'll have 1 QT extra water, in the 3 QT bucket.
4. Empty your 5 QT bucket, and put your extra 1 QT in it.
5. Now, fill your 3 QT bucket again, and pour it into the 5 QT bucket.

You now have 4 QT, exactly.

There is another way to do this:

1. Fill the 5 Qt bucket. Use it to fill the 3 Qt bucket. You now have 2 Qt left in the 5 qt bucket.

2. Empty the 3 Qt bucket and pour the remaining 2 quarts in the 3 Qt bucket. Fill the 5 Qt with water.

3. There is now room for 1 quart in the 3 Qt bucket. Fill the large bucket and use it to fill the remainder of the 3 qt bucket. There will be 4 quarts left.
