Water Buckets Interview Question

MDLFCS · 06-22-2010, 05:31 PM

You have 3-gallon bucket and a 5-gallon bucket. How can you use two buckets to make 4-gallons of water?

Watch Die Hard with a Vengeance.

There are two ways to solve this, maybe the question could be modified to say the 5 litre can doesn't fit under the tap...

Number 1

Fill the 5 litre can from the tap
Empty the 5 litre can into the 3 litre can - leaving 2 litres in the 5 litre can.
Poor away the contents of the 3 litre can.
Fill the 3 litre can with the 2 litres from the 5 litre can - leaving 2 litres in the 3 litre can.
Fill the 5 litre can from the tap.
Fill the remaining 1 litre space in the 3 litre can from the 5 litre can.
Leaving 4 litres in the 5 litre can.

Number 2

Fill the 3 litre can from the tap.
Empty the contents of the 3 litre can into the 5 litre can.
Fill the 3 litre can from the tap.
Empty the contents of the 3 litre can into the 5 litre can. - Leaving the 5 litre can full and 1 litre in the 3 litre can.
Poor away the contents of the 5 litre can
Poor the 1 litre from the 3 litre can into the 5 litre can.
Fill the 3 litre can from the tap.
Empty the contents of the 3 litre can into the 5 litre can.
Leaving 4 litres in the 5 litre can.

Tell the supply guys to order two 2 gallon buckets

Lol the first thing I thought of was Bruce Willis in Die Hard (though I don't remember what they did). Anyhow, I would use the 3 gallon container 3 times. Then use the 5 gallon container to take out 5 gallon. You're left with 4 gallon.

This was my impulse as well, but as I understand the question you are not provided a 3rd tank, meaning you must amass 4 gallons in the 5 gal bucket

the question in the movie involved only using the 2 containers. you couldn't use another container to store the 9 gallons of water

Just keep pour water from the 5 gallon jug to the 3 gallon jug three times...only fill up the 5 gallon jug only when its empty....and u'll end up to have 4 gallons in the 5 gallon jug
