Analytical, Puzzles, And Brain-Teasers Questions & Answers
1. If you have an infinite supply of water and a 5 Quart and 3 Quart Pail, How Would You Measure Exactly 4 quarts?
2. IF you could remove any of the 50 states, Which State Would IT be and why?
--I would not remove any of the definition of state is the definition of state is the
USA
's states). Could you imagine the gerrymandering after Something Like That? Besides - Each State Has Something Special It Brings To Its Star on The Flag. That Is What Makes Tha
USA
So remarkable.
--I Will Ask the interviewer for the definition of "Remove" First.if (The Answer IS Dig A Hole, Let Water Bubble Up) {I Would Say I "Remove" a state lack of water supply.} Else} answer is give it up or give it away to other countries) {I would say it's some state with the biggest area of desert. And I would definitely trade sth. back from whom want it} else // default, {I will keep it For Possible Future Usage}
3. IF you are on a boat and you throw out a suitcase, WILL THE LEVEL OF Water Increase?
- The Answer IS: IT Depends on The Density of the BRIEFCASE. While The BRIEFCASE IS IN THE BOAT, IT WILL Displace It's Weight in Ware.
IF The briefcase floats after you Toss It Out, The It Still Display ITS Weight In Water, and There Is No Change.
However, if the briefcase is Heavier Than Water IT Will Displace ITS Volume, Not ITS Weight. The Amount of DisplayD Water Will Be Less (Which is why it sank) and the water level will decreage.
- The Other Question IS WHETHER OR NOT The Suitcase Is Thrown in The Water. IT ITN ON TO A DOCK OR LAND, THEN The Level Will Decrease Due To Less Weight in The Boat.
4. There Are 3 Ants At 3 Corners of a Triangle, They Randomly Start Moving Towards Another Corner. What Is The Probability That The CORNER COLLIDE? - 1. Let's Mark The Corners of The Triangle AS A, B, C. 2 . Therenow The Ants Won't collide: a-> b, b-> c, c-> a and a-> c, c-> b> A3. There, probability of ants NOT COLLIDING: 2/8 = 1/4.
--- This assumes that ants move in a straight line, as we know they do not. They move all over the place, in random directions, eventually ending up in their final destinations. Although Microsoft asked me this question and was looking for The answer exerciseed by Other Posters, They Gave Extra Credit for what i expend.
--- you are all wrong! You have much not one but three obvious assumptions! 1) THEY START WITHIN THETEYTHININ THE CONFINES OF THE TRIANGLE.
Moral: Think Out of the Triangle !!
5, Three Men WERE RENTING A Motel Figuring The Room Cost 30 Dollars The Room Was Only 25 So The Bell Gave The Bell Boy Ten (Tip) The Bellboy Didn "T Think That Would Be Fair So He Gave Them Each Back 1 Dollar And Kept 2 for Himself. What happened to the other dollar? (SENT by macsabastion@webtv.net)
Oh After Giving It Some Thought actually I Was Right, There isn't any missing dollar.
If you go backwards you come up to this: 9x3 = 2727 2 = 29so it had to be 30 $ in Order to Be Correct Right? No, Because You Have to Add 3 $ and not 2. You Think It Would Be Right IF You Add 2 $ BECAUSE TIP IS That Amount. But The Tip is Already Included in The Multiplication.so The Maths Aren't Right, IT Should BE 9x3 3 and NOT 9x3 2.6. "You Have B Boxes and N Dollars. If I Want Any Amount of Money from 0 to Hand Me 0 to B Boxes SO That I get Exactly What I Request." The Two Questions Were "What Are THE RESTRICTIONS ON B and N, AND How is MONEY DISTRIBUTED AMONG THE BOXES? "
Trick is of binary number Numbers
2 ^ 0 = 12 ^ 1 = 22 ^ 2 = 42 ^ 3 = 82 ^ 4 = 16 .......
2 ^ 7 = 128 ...
THE FORMULA IS [LOG N to Base 2] 1 = bwhere [] Denote Integral Part of The Log Base 2 of N
Exampleso if we want 0 to 15 DOLLARS [log of 15 to base 2] 1 = [3.90] 1 = 3 1 = 4 Boxeswe Need to Have 4 Boxes Each Having 1, 2, 4, 8, DOLLARS Respectively.Now WE KNOW From Binary Numbers That Any Amount from 0 to 15 Can Be Formed with this Boxes.
For 0 to 6 DOLLARS [log of 7 to base 2] 1 = [2.58] 1 = 2 1 = 3 Boxeswe Need to have 3 Boxes Each Having 1, 2, 4, DOLLARS Respectively
For 0 to 100 dollars [log of 100 to base 2] 1 = [6.64] 1 = 6 1 = 7 Boxeswe Need to Have 7 Boxes Each Having 1, 2, 4, 8, 16, 32,64 DOLLARS Respectively

7. What is the amount of the number number from 1 to 1000?
Depends What Number Means Here:
If Means Integer, That's 100 * (100 1) / 2 = 5050; if NOT, That's Infinity.
8, You are an employer. You have ten employees. Each month, each one of your ten employees gives you ten bags of gold. Each bag of gold has ten pieces of gold in it. Each piece of gold weighs one pound. One of Your Employees Is Cheating You by Only Putting Nine Pieterials of Gold in Each of His Ten Bags of Gold. You Have A Scale (Not A Balance, A Scale), And You Can Only Take One Measurement from The Scale, ONLY ONE (1) reading. How can you tell which of the ten employees is cheating you by using this scale and only taking one measurement? --- When your employees come to pay you at the end of the month, take one bag from employee number one's pile and Set it aside. Take Two Bags from Employee Number Two's Pile and add it to one from Employee Number One. Take Three from Employee Three, Four from Employe Four, ETC ...
ONCE You Have Now Compiled A Pile of Bags (One from One, Two from Two, ETC). Set The Whole Pile (All 55 Bags) on the scale and take aread. If all the bags were honest You Would Have 550 Pounds on The Scale.
If employee one is cheating you, then the reading would be 549, since you only have one bag from employee one. Likewise, if the measurement is 547, then 3 pounds are missing, and employee three is the thief.
--- I Think WE Are Given a scale not a balance. So we can't Tell The Exact Weight of the Bags. So How do We Find Out WHETHER ITS 549, 547 ETC.?
--- Why does He Need to weigh? Can't He Just Count?
9, How Many Points Are The Place Where North You Reach The Place WHERE You Started.
--At The North Pole, The South Pole Wouldn't Quite Work, Since You Can Only Go North From The South Pole.
--Both answers (North Pole, and all points on the circle 1 mile north of the circle having circumference of 1 mile around the South Pole) are right.10, How would go about finding out where to look for a book in a library ? (You do not know how the books are organized beforehand)
- I WOULD Go AND ASK a Person in Charge of Arranging The Books Instead of Wasting My Time In Searching All of Them
- This Question is Open end, Thought Microsoft Might Be Testing Fundamentals on Binary Search, Indexing etc By asking this.
The approach I would take is, check out the index cards and find the shelf where the book is located. Then do an alphabetical search by physically going to that shelf. You can also say that you would start on the top of the shelf or the Bottom Depending on The "Letter" Name of The Book etc.
- I Would Leave The Library, Drive To The Exact Location of The Person Wro Wrote this Question, and SLAP Them.
11, Imagine you are standing in front of a mirror, facing it. Raise your left hand. Raise your right hand. Look at your reflection. When you raise your left hand your reflection raises what appears to be his right hand. But when you Tilt Your Head Up, Your Reflection Does Too, And Does Not Appear To Tilt His / Her Head Down. Why Is It That The Mirror Appears To Reverse Left and Right, But Not Up and Down?
- It's Mainly Because Man Himself Is "Left-Right" Symetric But Not "Up-Down" Symetric.
- this is not a Physics Issue ... this is a matter of perception.
WHEN You Stand in Front of the Mirror and Raise Your Left Hand, The Reflection is of Your Left Hand.
By referring to "what appears to be his right hand" the question has essentially asked you to envision yourself rotated 180 degrees about a vertical axis, thus subtly introducing the apparent conflict between left and right.Why it works: Since humans are relatively symmetric along A Vertical Axis You Are Able To Envision Your Left Hand Asia Right Hand for your Reflection.
Humans Are Not Generally Symmetric Along a Horizontal Axis (Hey, I've Never Seen It, But That Doesn't Mean Some Freak isn't out there ...), SO it's much harder to envision feed as a suitable head and vice Versa.
12, You Have A Bucket of Jelly Beans. Some Are Red, Some Are Blue, And Some Green. With your favor SAME?
IF you select 4 Jelly Beans You Are Guaranteed That You Will Have 2 That Are The Same Color.
13, You are given a scale which you are to use to measure eight balls Seven of these balls have the same weight:.. The eight ball is heavier than the rest What is the minimum number of weighs you could perform to find the heaviest of The Eight Balls ?. Remember It's a scale not a balance. (IE IT IS Heavier Tell You ether it can't give you the exact weight).
!. Umm. You can do this in 2 weight side of the scale. That's a Total of Six Balls You're weighing. If the three balls on each side weigh equally, you know that one of the two remaining balls is the heaviest. Weigh those two balls to determine which one is heaviest. If, however, one of the three ball combinations weighs most, remove all balls from the scale, then weigh just two of the three "heavier" balls. If those two balls are equal weight, the third, unweighed ball is the heaviest; otherwise the scale will indicate which of the two balls on the scale is the heavier one.So, what's the difference between a balance and a scale?
14. How Would You Design A TOASTER?
1. Find Out Voltage to Besu Supported2. '' '2-pin / 3 PIN PIN PIN PLUG? 3.' '' 'How Many Slots for Bread? 4.' '' 'What Size Bread? 5. Automatic Pop-Up 6 . Easily accessible for cleaning and maintenance7. Easily operable8. Compact and good looking9. Design a simple circuit that uses components that are easily available.10. Internet enabled? 11 (?). Provide a place to keep the stack of bread slices, a Settable Counter, Place To Keep The Plate, TOASTER Automatically Chicks Up Bread from The Stack, "Toasts" it and place it on the place.
12. Also could provide a butter holder that melts the butter and sprinkles it on the toast, once done. 13. Optional alarm that rings after the job is done (entire stack is toasted) 14. Optical sensor to sense the actual browning of the Bread (Different Settings for Wheat and White Bread)
.. and so on .... :))
15. How Would You Design AN Universal Remote Control?
16. How Would You Design A CLOCK for A BLIND PERSON?
I would design a clock with Brail Code, Self talk and vibration and with capabilities for disabling any of those features depending on the requirement. Since vibration is very difficult to design, they can be set aside in another version of the clock.17. How Miles Of Road Are The Us?
- This Series of Questions Is Called Guesstimates, And Tests
UR
Ability to make Meaningful Guesses and assumptions. Some 帖子 帖子
US
Annually? '
- actually this questions is like that: how many cars in USA u can answer any number u want and argue later: ask the interviewer to count them for u, if he finds more cars than, more cars have been bought since he last counted ..., IF Less Then a Lot of Cars Have Been Scrapped ... The Same Thing Applies To Road Also, Enjoy
- i Guess this is funny !! I would rather Say, 0.625 Times the number of kms in
USA
:)
