Then there are 5 million family-owned piano, so there are five million across the United States piano. If every year of tuning a piano, a piano tuner tuning 1000 flights a year, then the United States the number of tuner is 5000000/1000 = 5000. The world's population of about 60 million, the United States 20 times, but the tuner is surely less than 20 times the United States, because the different levels of affluence and cultural level.

4 individuals across a tether bridge at night to return to their camp. Unfortunately, they only have only a flashlight to insist on 17 minutes. Must be holding a flashlight through the rope bridge, and the rope bridge you can only make it from the weight of two people. The four men are not the same speed over the rope bridge, rope bridge through the first 1 minute, the second two minutes, the third 5 minutes, the slowest that to 10 minutes. How can they all came in 17 minutes, the rope bridge?
A 1:1 +2 first off, 1 (or 2) return 5 +10 over 2 (or 1) return 1 +2 over
A 2: the slowest 10 minutes of activity in bridge flashlight , 1 minute and 2 minutes, had one, had finished in 1 minute, 5 minutes on the bridge swiftly. Had finished in 2 minutes, 10 minutes on the bridge with a flashlight, a absolute of only took 12 minutes to all past

A 2: 8 ball by any number of 2,3,3 divided into three groups: A, B, C. The B, C groups were placed at both ends of the balance, if both ends of the smooth, that is the same quality, just the A group of two balls were placed at both ends of the balance, downward-sloping side of the ball that is filled relatively heavy; if both ends of the slant, will be downward-sloping end of the three balls filled out, and then from three balls out of any balance two balls were placed at both ends. If both ends of the flat, so that the ball has not been taken relatively heavy; if both ends of the tilt, then the downward-sloping side of the ball that is filled is relatively heavy;
A 3:3-3-2 points that
5 pirates, along to position array from 5 to 1. Pirates of the largest share to intend how 100 gold coins they. But other human ought have the ballot, if the majority against, he would be killed. He ought inquire what kind of procedures, both to themselves to obtain as numerous gold coins without creature killed? (Hint: There is a pilfer can obtain 98% of gold)
A 1: 98,0,1,0,1
first start from the No. 5 Pirates, because he is the most secure,
Nike Shox Menn, the risk of the sea has not been dropped, so he is also the most simple strategy, that is the best person in front of all die out, then he can get it alone 100 gold coins.
then see 4, his contingencies of survival depends completely on the human in front of there living, for if 1 to 3 of the pirates were entire fed a shark, then only 4 and 5 in the circumstance, regardless of 4 on what the delivery blueprint, some will vote opposition the No. 5 to grant sharks to fared 4 to pocketed all of the coins. Even 4 to 5, amuse save your life and made (0,100) This exclusive program because 5 gold, but keep the No. 5 No. 4 may also feel that there is danger, and voted against and let it fared the sharks. Therefore, a logical 4 should not take such a hazard, the survival of wish in a irregular choice of 5, he can only advocate 3 in order to indeed vouch their own lives.
look at No. 3, he followed via the logic of reasoning, it will make (100,0,0) this delivery scheme, because he knows nothing even 4, it will unconditionally support or vote for him , then combined with their one vote can make him sure to conquer the 100 gold coins.
But No. 2 is No. 3 after reasoning that the allocation plan, then he will make (98,0,1,1) program. Because the program comparative to the distribution of program 3, 4 and 5 can at least get a gold, reason 4 and 5 will indeed find this program more beneficial for them to support 2, do not want 2 out by 3 to be apportioned. Thus, 2 can Pidianpidian take 98 gold coins.
Unfortunately, the first pirate more than cheat, after some insight into the reasoning even after the No. 2 distribution program. He will take the strategy is to give up 2, and 1 to 3 coins in the meantime to 4 or 5, 2 gold, that that (97,0,1,2,0) or (97,0,1, 0,2) distribution program. As the No. 1 distribution plan for the No. 3 and No. 4 or No. 5, the program can be compared to 2 to acquisition more benefits, then they will vote for No. 1, No. 1, plus one vote of their own, 97 No. 1, gold can lightly fall into the pockets of the.
Answer 2: If it is me. . . I will propose to lower levels than me who continue to consult on how this method points, so you can fall into a logical paradox. As long as the rules exactly, then I can not supply to dead. . . . .

you a 100-storey structures, to give you two eggs. Sometimes eggs are very fragile and periodically unusual tenacity. This means that, if dropped in the premier wafer of the eggs, the eggs may be broken, and if the level dripped from 100 eggs, eggs may be safe. This is accurate the same two eggs. You need to figure out, where the highest floor dropped when the eggs were broken. The question is, how many times you need to throw eggs to count the layer. Throughout the process, you are only allowed to destroy the two eggs.
A: 14. Let x egg throwing to test the F layer y times, then F = f (x, y). f (1,1) = 1,
Nike Shox Dreams, f (1,2) = 2 ... ... .. f (1, n) = n. f (2,1) = 1, for f (2,2), the first test time, if the first egg is not broken, then test the layer on top of layers of f (2,1), if the first break an egg , and then test the layer under the layers of f (1,1),
Nike Shox R5, so 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. Introduction of series: f (2, n) = n * (n +1) / 2. The solution, n = 14.
