click on image to enlargeHere is the latest quiz (from CEP) that I think the readership will enjoy – it is not multiple choice like the last one that several people admitted guessing some answers on their way to excellent scores.
Suppose you are given two buckets as shown above, one that holds exactly 5 gal of water & one that holds exactly 3 gallons of water & that neither bucket has any incremental measurement indications. How can you measure exactly 4 gal of water using these two buckets? Assume you have unlimited supply of water.
I will post all correct answers & send the solution to anyone who requests it if no one figures it out.
easy answer? combine two buckets, divide in half. OR, use a 1 gallon milk jug to take one gallon off the 5-gallon. OR, get a new bucket. Really too hot to figure it out!!
ReplyDeleteTwo people have gotten the answer by different methods. Will post in a few days.
DeleteImpossible. Can't be done.
ReplyDeleteLets get some toughies!
ReplyDeleteFill 5 gallon pail. Pour into 3. dump 3 gallon pail. Pour remaining 2 gallons from 5 g pail into 3 g pail. Fill 5 g pail. Top off 3 g pail with 1 gallon of water. 4 gallons remain in 5 g pail.
Hi Doug,
ReplyDeleteI am sorry for the delay.
I would put water into 3G bucket and dump into 5G bucket, fill water in 3G bucket again, dump 2G water to 5G bucket, empty 5G bucket, put 1G water (from 3G bucket) into 5G tank. Fill 3G bucket and put into 5G bucket, then I have 4G of water in the 5G bucket.
Not sure if this is correct but i would fill up the 5 gallon bucket and use that to fill the 3 gallon bucket , leaving 2 gallons in the 5 gallon bucket. Then i would dump the 3 gallon bucket.Then I would dump the remaining 2 gallons from the 5 gallon bucket into the three gallon bucket. At this point I have 2 gallons in the three gallon bucket and I would then refill the 5 gallon bucket. So at this point I have 2 gallons in the 3 gallon bucket and the 5 gallon bucket is full. I then take the 5 gallon bucket and use it to fill the remaining 1 gallon into the 3 gallon bucket, leaving me with 4 gallons in the 5 gallon bucket.
ReplyDeleteSolution: Empty out the 3 gal. bucket, then pour water from the 5 gal. bucket into the 3 gal. one. What is left is 2 gal in the 5 gal bucket. Mark the water level in and/or out of the 5 gal bucket. Fill the 5 gal bucket to the brim and pour into the 3 gal. bucket. Empty the 3 gal bucket and pour the left over 2 gal of water in the 3 gal. bucket. Lastly fill the 5 gal bucket up to the 2 gal marker and pour the contents of the 3 gal bucket into the 5 gal. one to yield exactly 4 gals.
ReplyDeletePls let me know if there are any other solutions.
You have the right idea but you used a marking pencil which is not part of the equipment. Please try again without marking the 5 gal bucket. So far there are two ways to work the problem that people have come up with. I will post all of them on RTE later this week.
DeleteYou are close.
Sounds so simple.
ReplyDeleteIf this is the same as someone else, sorry. This is what I came up with though.
Take the bucket of 3 gallons. Pour this into the 5 gallon bucket.
Fill up 3 gallon bucket. Add to 5 gallon bucket. Two gallons will go in and one will be left.
Empty the 5 gallon bucket and pour the one gallon in.
Then add 3 more gallons.
Here goes , will try my best,----- fill 3 gal. Bucket dump into 5 gal. Bucket.
ReplyDeleteAgain fill 3 gal bucket, than fill 5 gal bucket.
This leaves 1 gal in 3 gal bucket
Dump. 5 gal bucket, dump the 1 gal left in the 3 gal bucket which gives the 5 gal bucket with 1 gal,
Fill 3 gal bucket and dump into 5 , this will give you 4 gal lions in the 5 gallon bucket.
Hope I have this right.
Will be leaving Marco Island FL. this Saturday.
Dump the 5 gal. Fill 3 gal and add it to the 5 gal bucket. Fill 3 gal again and add sufficient amount to fill 5 gal bucket. Now you have one gal in the 3 gal bucket, transfer it to a large container. Fill 3 gal bucket and add to large container.
ReplyDeleteI was going to say that I'd fill the 3 gallon bucket, pour it into the 5 gallon bucket. I'd fill the 3 gallon again and use it to fill the 5 gallon bucket to the top, leaving 1 gallon remaining in the 3 gallon. Then I'd empty out the 5 gallon and pour my remaining 1 gallon into the 5 gallon bucket. Then I'd fill the 3 gallon bucket again and pour it in with that 1 gallon, creating 4 total.
ReplyDelete3 gal 5 subject : I would take the full 3 gal. bucket, and pour it into the 5 gal. bucket. Now fill up the 3 gal. bucket, and and use this to fill the 5 gal. bucket to the top. This will leave one gal. left in the 3 gal bucket. Now empty out the 5 gal. bucket and put the remaining one gal. into the empty 5 gal..Now fill the 3 gal.bucket an d pour it into the 3 gal,and pour it into the 5 gal bucket which has one gal. End result 4 gal in bucket. Let me know if this makes any sense.
ReplyDeletehas to be some kind of formula you use, that was never one of my strong points.
ReplyDeleteI try to outguess the mkt, sometimes you win,other times you lose, but mkt looks top heavy-due for decline around Oct.or so see what happens say hello to Carol
Hi Doug,
ReplyDeleteHere's my Solution #1;
Fill 5 gal. bucket with water and pour into the 3 gal. bucket leaving 2 gal. Empty the 3 gal. bucket and transfer the 2 gal of water from the 5 gal. to the 3 gal bucket. Now fill the 5 gal bucket with water and pour the contents(1 Gal) into the 3 gal. bucket till full, leaving behind exactly 4 gals in the 5 gal. bucket.
Solution #2:
Fill 3 gal. bucket with water and transfer the contents to the 5 gal.one. Repeat this step one more time till 5 gal bucket is full, leaving 1 gal. in the 3 gal bucket. Empty the 5 gal. bucket and transfer the 1 gal of water from the 3 gal bucket to the 5 gal one. Lastly fill the 3 gal. bucket with water and pour the contents into the 5 gal. to yield a total of 4 gals (1+3).
