1, problem: a school bus can hold much golf next?
Read KWIC "school bus" "hold," "golf", the question "how many." What is the use of school buses, dedicated to carrying students inside the school educators. What golf Yes. A sports equipment. Or a commodity (not to consumers). In short one kind of goods. We have a common sense, can only truck shipments, while passenger cars and the like can not be used for shipping the goods, or violation of traffic laws. So, we can easily see the. In fact, he is not the subject of our judgment test volume. But whether we understand the relevant knowledge. Product Manager position is that we not only take into account technical feasibility, but also consider the relevant laws and regulations, people can not stand. Do the products developed very well, but can not be marketed or not consumers.
So the answer is a can not be installed. Because school bus carrying students and educators to use. It can not be used to hold the goods.
Suppose bus capacity = 3 × 4 × 25 = 300 cubic meters, a golf radius of about 10 cm, because there is a gap after loading, in accordance with the count cubic volume of about 0.008 cubic meters, so that vehicles can accommodate correction 300 / 0.008 = 37500 golf.

4. How many of the world piano tuners?
Answer 1 : a woman two, a man of
Answer 2 : speaking to a customer, because of the work done as well, so all can be outsourced out
Answer 3 : This question needs to know that the US population and general economic conditions, in order to estimate. A total of 300 million US population, according to a family of three, the United States a total of 100 million households, that is, if half of the 50 million households belong to affluent families, with piano proportion of 10% this ratio may be a bit high, but the estimated approximate ratio when are allowed. So there are five million households own a piano, so the United States there are 5 million piano. Assuming that each piano tuning once a year, a tuner tuning the year 1000 sorties, then the United States the number of tuners is 5000000/1000 = 5000. The world's population of about 60 million is 20 times the United States, but the tuner is certainly less than 20 times the United States, because of the different levels of affluence and cultural level. But do generally estimated that the number of tuners United States accounts for about a quarter of the world, the world of tuner should have 2 million people.
5. manhole cover on the road, there is definitely something hold him at the edge of the covers, the covers will not fall, and this edge is very small. So manhole covers are round, then, is equal to the radius, if for some reason playing covers Since then its side longer than the diameter of the edge, so that the covers will not fall., while there is always an inner diameter of other shapes is the longest, such as rectangular, it is longer than the diagonal side length of the rectangle is made if the covers, it is most likely to fall from a diagonal angle. So always make manhole covers round. Later, it covers the whole world round.

The B, C groups were placed at both ends of the balance, if both ends of the flat, i.e., equal mass, the balls just two group A were placed at both ends of the balance, an end of the downwardly inclined ball that is filled heavier; if inclined ends, one end of the downwardly inclined will hold three balls out, then from any three balls extracted two balls were placed at both ends balance. If both ends of the flat, so that the ball has not been drawn comparatively heavy; if inclined ends, the end of the downwardly inclined ball Sheng i.e. is relatively heavy;
Answer 3 : sub-called 3-3-2
5 pirates, according to a ranking from 5-1. The top pirate has the right to propose how 100 gold coins. But the others get to vote, if the majority of opposition, he would be killed. He should ask what kind of program, both for myself to get as much gold it will not be killed? (Hint: One pirate ends up with 98 percent of the gold)
A 1 : 98,0,1,0,1 first from the No. 5 Pirates began, because he is the most secure, no risk was dropped sea, so his strategy is also the most simple, that is the best person in front of all dead bare, then he can only get it one hundred gold coins. Then look at No. 4, his chances of survival depends entirely on the front there are people alive, because if the Viking 1 to No. 3 are all fed the sharks, then only in the case of No. 4 and No. 5, No. 4, of the matter What kind of allocation scheme, No. 5 will certainly vote to make 4 to feed the sharks to pocketed all the gold coins. Even No. 4 in order to protect life and please the No. 5 proposes (0,100) This program allows exclusive gold No. 5, No. 5 but also may feel dangerous to keep No. 4, and voted against and let it feed the sharks. No. 4 is therefore reason should not take such a risk, the survival hopes on randomly selected No. 5, No. 3 in order to support his only absolute guarantee of their own lives. Let's look at No. 3, he passed after the above logical reasoning, will propose (100,0,0) This allocation scheme, because he knows nothing even No. 4, still will support him unconditionally and to vote in favor, then coupled with their one vote can make sure to win him the 100 gold coins.
However, No. 2 has also been reasoning that the allocation No. 3, he would propose (98,0,1,1) program. Because this program with respect to the allocation scheme No. 3, No. 4 and No. 5 at least get a gold, rational Nos. 4 and 5 will naturally feel that this program more beneficial for them and support No. 2, does not want No. 2 out and to allocate the numbers 3. In this way, you can pidianpidian No. 2 took 98 gold coins.
Unfortunately, the No. 1 pirate more than fool, after some lapse of insight into the reasoning allocation scheme No. 2. He will take the strategy is to give up No. 2, and No. 31 to the gold coins, and to No. 4 or No. 52 gold coins, namely that (97,0,1,2,0) or (97,0,1, 0,2) allocation scheme. As the No. 1 distribution plan for the No. 3 and No. 4 or 5, the No. 2 program can be compared to get more benefits, then they will vote for No. 1, No. 1 plus 1 vote itself, 97 coins can easily fall into the pockets No. 1
Answer 2 : If it is me. . . I will propose to make lower level than my people continue to negotiate how to divide this method, so you can fall into a logical paradox. Just exactly as the rules, then I can not afford to die. . . . .
You are reduced to only the thickness of the coin so the high points (not compressed, scaled-down), and then thrown into an empty glass stirrer, the stirring blade starts to rotate after one minute. what would you do?
A : agitator should be voided, so hide the edge should not be hit. But glass stirrer four weeks may not be able to seize the attachment, the rotation caused by wind may blow you up. So try to come to the middle agitator shaft, trying to climb or catch.
Answer 2 : how to escape from the mixer? (1) to climb along the measurement scale;
(2) unscrew the glass stirrer;
Stream (3) by the rotation of "fly out".

You are in a 100-storey building, giving you two eggs. Sometimes the eggs are very fragile, sometimes abnormal tough. This means that if threw eggs, eggs in the first layer might be broken, and if it is dropped eggs, eggs from the 100th floor probably safe. This is exactly the same two eggs. You need to figure out, from which the highest floors dropped, eggs are not broken. The question is, how many times you need to throw eggs in order to calculate the floor. Throughout the process, you are only allowed to break two eggs.
Answer : 14 times. Let x of y can throw eggs test layer F, then F = f (x, y) . f (1,1) = 1, f (1,2) = 2 ...... ..f (1, n) = n. f (2,1) = 1, for the f (2,2), a first test, if an egg is not broken first, the test on the number of layers of the layer f (2,1), if the first eggs broken, the number of layers beneath the test layer is f (1,1), so that f (2, n) = 1 + f (1, n-1) + f (2, n-1). Thus f (2,1) = 1, f (2,2) = 3, f (2,3) = 6, f (2,4) = 10, f (2,5) = 15, f (2, 6) = 21. Release series: f (2, n) = n * (n + 1) / 2. The solution, n = 14.

Question: How many a school bus can hold golf?
In view of this question is to ask the product manager, is unlikely to test its "honesty" and "attitudes", so the interviewer does not want "do not know" answer. Because it is not the product manager, marketing manager, will not test the ability of the human brain teasers, does not want "school bus load number of how many will be able to hold golf." I think there might be a test site to estimate the ability of candidates to test how sensitive his first reaction to digital, because the same is estimated at almost totally unknown when planning to do the project, then the answer should be like this: Suppose school bus volume = 3 × 4 × 25 = 300 cubic meters, a golf radius of about 10 cm, because there is a gap after loading, in accordance with the count cubic volume of about 0.008 cubic meters, so that vehicles can accommodate correction 300 / 0.008 = 37500 Golf .
Question: If you had to clean all the windows in Seattle, how much it will give you the asking price?
This problem is likely to test the project manager is the face of the decision-making ability is unknown, given Google's bold, it may not be the answer: I do not do it, because the income and expenditure not directly proportional, my life there is no opportunity to clean all the windows. The answer may be Google's style, if I could invent a more rapid window cleaning tool, then I will provide an almost free cleaning work, so when I can not do without every window, I can start devoured the asking price .
Question: hands of the clock will coincide with a day total of how many times?
I remember elementary school math test before this question was asked is how many times the hour and minute hands overlap in a day, the answer is 23, because 24 is already next day. This question is when it coincides with a three-pin test every minute how many times a day, then how count it, the same answer. No need to consider the second hand, because the second hand only once every minute and the other two needle overlap, that is not necessary to consider the second hand, the answer is still 23 times.
Problem: A man drove up to the hotel, get nothing. What really happened?
Apparently to test the software engineer's imagination. American motels generally have a lot of prostitutes, prostitutes certainly not stupid enough to just sell the flesh, when a person is exposed when the original desire is that the most vulnerable time, but how to do nothing. Who can steal credit cards, car keys can be stolen, hand ring can steal your mouth, then his wife called and family can also be taken away ...... but the blood of the family and company how to lose You also need to think about, certainly more than one prostitute. Perhaps a little fanciful, a man came to the motel, his family seat and the seat of the company was an earthquake, all dead, and met a prostitute.
Question: You are the captain of a pirate ship, your crew to decide how to split the vote bullion. If agree with you less than half the number of crew members, you will be killed. How do you propose should be allocated bullion can not only share more stolen goods, but also to survive?
Tears ran, why foreigners are so pure, primary school we have done such a question, that question I'll never forget: a landlord for farm laborers harvesting seven days, a daily reward gold bars, seven gold bars together, only breaking twice daily completion She neither account nor debts, how to pay the bill? The answer is: a first breaking "a", and then breaking off a "two" left a "four." On day 1, pay "a"; 2 days, collect "two" for "a" back; day 3, pay "a"; 4 days, pay "four" exchange "a", "two" ; day 5, pay "a"; 6 days, collect "two" exchange "a"; 7 days, pay "a." Google's This question is a variant of junior high school math problems.
This problem can simplify understanding, suppose you have five pirates, grabbed one hundred precious stones, to be allocated, as others are not satisfied will be sent to feed the fish. From the top (so that it is 1) Pirate proposed distribution plan, then five people vote, if and only if more than half of the people agree that it is distributed according to Proposition 1, otherwise, he will be thrown into the sea to feed sharks.
According to the meaning of problems, with the following analysis: As the five pirates are very sensible people, so we must first Viking 1 "save his life" to be able to maximize their own interests, which is both the prerequisite to solve this problem It is also a constraint. Therefore, in accordance with the meaning of the questions, he must win at least two pirate support to the proposal satisfies this condition in the remaining four pirates, but the pirates apparently rational No. 1 only win the support of two pirates enough. 2 is obtained wherein the support pirates, two conditions must be met: a, the same amount of the two gem assigned to pirate. b, the number of stones in the hands of pirates these two should not be less than (or even more than) the number of pirates in the hands of No. 1 gem. Jewels set up No. 1 in the hands of pirates is X, the number of pirates in the hands of two Viking stones are for a Y, there are clear meaning of the questions, the number of No. 1 pirate pirates in the hands of two gems do not need to strive for completely zero (because with his own, a total of three people support the distribution plan, its goal has been achieved). Thus, the problem is converted into mathematical language to describe, it is: at the X≤Y, seeking to satisfy the relationship X + 2Y = X when the maximum value of 100. Methods for solving linear programming, the optimal solution can be obtained as X = 32, Y = 34. Therefore, in order to maximize their own interests under the given constraints, Viking 1 allocation scheme proposed should be: (32,34,34,0,0).
Question: You are a 100-storey building, giving you two eggs. Sometimes the eggs are very fragile, sometimes abnormal tough. This means that if threw eggs, eggs in the first layer might be broken, and if it is dropped eggs, eggs from the 100th floor probably safe. This is exactly the same two eggs. You need to figure out, from which the highest floors dropped, eggs are not broken. The question is, how many times you need to throw eggs in order to calculate the floor. Throughout the process, you are only allowed to break two eggs.
Whoever is able to know the result of such a mental arithmetic problem, and that only certain people often do this question, 14 times. Let x of y can throw eggs test layer F, then F = f (x, y). f (1,1) = 1, f (1,2) = 2 ...... ..f (1, n) = n. f (2,1) = 1, for the f (2,2), a first test, if an egg is not broken first, the test on the number of layers of the layer f (2,1), if the first eggs broken, the number of layers beneath the test layer is f (1,1), so that f (2, n) = 1 + f (1, n-1) + f (2, n-1). Thus f (2,1) = 1, f (2,2) = 3, f (2,3) = 6, f (2,4) = 10, f (2,5) = 15, f (2, 6) = 21. Release series: f (2, n) = n * (n + 1) / 2. The solution, n = 14.
Question: Have you reduced to only one-fifth of the coin is so high, your quality proportionately reduced to maintain unchanged the original density. You are then thrown into an empty glass blender, stir blade will start running in 60 seconds, how can you do?
If you reduce the size of a coin, when the blade is no longer sharp for me. To escape death you may only need to climb on top. As we have seen large cement mixer used in the construction site inside the blade, for humans if it is not standing still pose a threat. Moreover, as far as possible to stabilize himself in the middle of the container, if not thrown by centrifugal force to, stirring blades will not be torn. But I do not think they can survive in this state, so I chose to commit suicide.
