The man replies ' Nine. I am German. But how did you know my name was Walter!' 0 Share this post Link to post Share on other sites

0 Posted 14 Jan 2008 · Report post hmmmm.... methinks it's more than that.... Cos if 50% of pole is in the ground and 33% (one third) is in the water then only 17% is sticking out of the water. The eight feet represents 17% of the total length of the pole there fore the total length is 331 feet! 0 Share this post Link to post Share on other sites

I'm not sure what how you're performing your calculations, but using the percentage data, I was able to come up with 47 and a fraction. How I [originally] calculated it: x/2 + x/3 + 8 = x x/2 + x/3 -x = -8 3x/6 + 2x/6 - 6x/6 = -8 -x/6 = -8 -x = -48 x = 48 0 Share this post Link to post Share on other sites

0 Posted 6 Feb 2008 · Report post The answer is absolutely 48 feet. 1/2 + 1/3 = 5/6 1/6*x = 8; where x = length of the pole x = 48 Nice puzzle. I haven't manually added a fraction in a long time! 0 Share this post Link to post Share on other sites

The problem states: "One half of the pole is in the ground, another one third is covered by water and eight feet is out of the water." Another- would imply 'in addition to' or 'along with' So why would one assume that this reffering to a fraction of the entirety?

0 Posted 13 Feb 2008 · Report post I'm thinking 12' is correct also. That would leave 6' in the ground 4' in the water and 2' in the air.The 6' in the ground and the 2' in the air are both out of the water and 4' is 1/3 of the total 12' . 0 Share this post Link to post Share on other sites

0 Posted 18 Feb 2008 · Report post The answer is 48. As the problem states, 1/2 (or 3/6) of the pole is in the ground, another 1/3 (or 2/6) of the ENTIRE LENGTH is in the water, the remainder, being 1/6, is 8 feet. 8X6 = 48. If you assumed that the 1/3 is considering only the part that is NOT in the ground you would receive a different answer, but the problem does not say that. It is funny to watch you all argue over such a simple calculation. This isn't really much of a brain teaser so much as it is a word problem. 12 is not the answer: 1/2 of 12 is 6. How can a the part of the pole, which is 8 feet long, be LONGER than the remaining piece of pole (6ft)? Check your answers to make sure they make sense before answering.... I hope none of you are engineers, because in the real world you don't get to argue over a problem statement. -1 Share this post Link to post Share on other sites

0 Posted 20 Feb 2008 · Report post I'm with Emapher on this one. the word "another" dictates that the 1/3 covered by water does not include the length of the pole in the ground. if.. if.. the original question had left out that word, then you would be correct. i.e. 1/2 is in the ground, 1/3 is under water. but when it was worded like 1/2 is in the ground, another 1/3 is under water.. it takes on a different meaning. The answer.. as worded in the original question, is 24 feet. 0 Share this post Link to post Share on other sites

0 Posted 23 Feb 2008 · Report post you know you could just change the denominator of 1/2 and 1/3 to 3/6 and 2/6 which are equivlent fractions, then just find whats left which is 1/6 and then multiply be 8 hears an example 1/2=3/6 1/3=2/6 3/6-2/6= 1/6 1/6=8ft. 8*6=48ft 0 Share this post Link to post Share on other sites

0 Posted 28 Feb 2008 · Report post There is a pole in a lake. One half of the pole is in the ground, another one third is covered by water and eight feet is out of the water. What is the total length of the pole in feet? The answer is 24 feet. Don't worry about the half of the pole in the ground just yet. Of the half of the pole NOT in the ground, two thirds are out of the water, which is 8 feet, making the one third covered by water 4 feet. Four plus eight equals twelve. Therefore, the length of the pole NOT in the ground is 12 feet, and since half of the pole is in the ground, the length of the pole is 24 feet. 0 Share this post Link to post Share on other sites

0 Posted 28 Feb 2008 · Report post The pole is 12'. It states that 8' is out of the water which should include the half that's on the ground. So if 4'(12'/3') is in the water the pole is 12' and for the 8' that's out of the water... half of 12' is on the ground so 6' and the remainder is 2'. |\\\\\\\\\\\\| <- 12' total pole length |\\\\--------| <- 4' the 3rd that's in the water |------\\\\\\| <- 6' half of the 12' + |----\\------| <- 2' the remainder = |----\\\\\\\\| <- 8' that's out of the water 0 Share this post Link to post Share on other sites

Therefore, depending on how you take the wording of the puzzle, the pole is either 48, or 12 feet long. 0 Share this post Link to post Share on other sites
