How many golf balls can fit in the school bus?Assuming it's referring to a particular bus that you have in your possession, your best bet is to determine its volume somehow. You might try filling it with a known quantity of fluid, but it would probably leak too much to get an accurate measurement and golf balls can't occupy every feasible space that a liquid might. Perhaps your best option would be to acquire or create a CAD model of the bus's interior and fill that with virtual golf balls using a physics simulation.
How much should you charge to wash all the windows in Seattle?The best way to think of this issue is not in terms of how many windows you must wash, but rather how much surface area you must cover. A window washer will be able to wash 'x' amount of area per hour. The surface area can be approximated for every building from architectural drawings; include the entire surface area of each side of each building (including areas not covered by windows) so as to account for costs incurred from particularly difficult buildings to clean. Charge enough money to hire enough washers to clean the required surface area in the time allotted.
How many piano tuners are there in the entire world?Presumably you'd need to identify trends in #'s of tuners per capita for every city/country and extrapolate from there. Your data would come from phone-books and other business directories.
Why are manhole covers round?The typical answer is "to prevent them from falling through the hole" but it could also make moving the heavy covers around easier as you can roll them. A round edge may cause less damage to tires should it ever stick up above the road surface.
Design an evacuation plan for San FranciscoTough to do without extensive research, but I'm guessing the fastest evacuation would be via the harbor on ships as California's road network is notoriously congested.
How many times a day does a clock’s hands overlap?An episode of British trivia game-show"QI" revealed that they overlap 22 times a day, not 24 as many suspect. I forget their explanation for this but you can prove it by fast-forwarding a clock and counting each overlap.
Explain the significance of "dead beef"A Google search shows this to be an obscure reference to a programming dialect known as
Hexspeak. Presumably this question is directed towards those applying for programming positions.
A man pushed his car to a hotel and lost his fortune. What happened?Perhaps the hotel was also a casino?
You need to check that your friend, Bob, has your correct phone number. Ask him in a way that no one will find out YOUR phone number if they were listening to you conversation.I believe a
checksum would do the trick.
You're the captain of a pirate ship…and your crew gets to vote on how the gold is divided up. If fewer than half of the pirates agree with you, you die. How do you recommend apportioning the gold in such a way that you get a good share of the booty, but still survive?Promise any pirate that agrees with you a split of a percentage of the gold proportional to the percentage of pirates that agree with you, and those that disagree can split the remaining percentage of the gold. If there are 10 pirates and six agree with you, they'd each get a cut of 60% of the loot; this means every pirate gets an even cut regardless of whether or not they agree with you
but it
sounds like agreeing with you gets them more gold.
You have eight balls all of the same size… 7 of them weigh the same, and one of them weighs slightly more. How can you find the ball that is heavier by using a balance and only two weighings?First weighing - Put 3 balls on each side. If one side is heavier isolate the three. If neither side is heavier isolate the two balls that weren't weighed.
Second weighing - If three balls remain, put one ball on each side. If each is equal the heavier ball is on the table. If two remain, weigh both and find the heavier one.
Explain a database in three sentences to your eight-year-old nephew.A database is like a store with the shelves being lined with toys. Every toy has a name, a place on the shelf, and a price. A database can store anything though, not just toys; it just keeps it in a digital form on a computer.
You are shrunk to the height of a nickel… and your mass is proportionally reduced so as to maintain your original density. You are then thrown into an empty glass blender. The blades will start moving in 60 seconds. What do you do?Nothing; if you are as tall as a nickel the blades will be well above your head even if you stand up. It wouldn't be pleasant though.
