Each person will be assigned either a red hat or a blue hat. No one can see the color of his or her own hat. However, each person is able to see the color of the hat worn by every person in front of him or her. That is, for example, the last person in line can see the color of the hat on 99 persons in front of him or her; and the first person, who is at the front of the line, cannot see the color of any hat.Beginning with the last person in line, and then moving to the 99th person, the 98th, etc., each will be asked to name the color of his or her own hat. If the color is correctly named, the person lives; if incorrectly named, the person is shot dead on the spot. Everyone in line is able to hear every response as well as hear the gunshot; also, everyone in line is able to remember all that needs to be remembered and is able to compute all that needs to be computed.Before being lined up, the 100 persons are allowed to discuss strategy, with an eye toward developing a plan that will allow as many of them as possible to name the correct color of his or her own hat (and thus survive). They know all of the preceding information in this problem. Once lined up, each person is allowed only to say “Red” or “Blue” when his or her turn arrives, beginning with the last person in line. </p><p>Develop a plan that allows as many people as possible to live.</p>Sumedhhttp://www.blogger.com/profile/11533458660230230361noreply@blogger.com4tag:blogger.com,1999:blog-2267127033347614408.post-86714841996598076272009-08-30T21:42:00.000-07:002009-08-30T21:42:00.153-07:00What was his salary to begin with?<span style="font-size:85%;">A worker earns a 5% raise.

Out of which one is odd one i.e weight is less or more. How many iterations of weighing are required to find odd coin?<br /><br />Answer:<br /><br />It is always possible to find odd coin in 3 weighings and to tell whether the odd coin is heavier or lighter.<br />1. Take 8 coins and weigh 4 against 4.<br />o If both are not equal, goto step 2<br />o If both are equal, goto step 3<br /><br />2. One of these 8 coins is the odd one. Name the coins on heavier side of the scale as H1, H2, H3 and H4. Similarly, name the coins on the lighter side of the scale as L1, L2, L3 and L4. Either one of H's is heavier or one of L's is lighter. Weigh (H1, H2, L1) against (H3, H4, X) where X is one coin remaining in intial weighing.<br />o If both are equal, one of L2, L3, L4 is lighter. Weigh L2 against L3.<br /> If both are equal, L4 is the odd coin and is lighter.<br /> If L2 is light, L2 is the odd coin and is lighter.<br /> If L3 is light, L3 is the odd coin and is lighter.<br /><br />o If (H1, H2, L1) is heavier side on the scale, either H1 or H2 is heavier. Weight H1 against H2<br /> If both are equal, there is some error.<br /> If H1 is heavy, H1 is the odd coin and is heavier.<br /> If H2 is heavy, H2 is the odd coin and is heavier.<br /><br />o If (H3, H4, X) is heavier side on the scale, either H3 or H4 is heavier or L1 is lighter. Weight H3 against H4<br /> If both are equal, L1 is the odd coin and is lighter.<br /> If H3 is heavy, H3 is the odd coin and is heavier.<br /> If H4 is heavy, H4 is the odd coin and is heavier.<br /><br />3. The remaining coin X is the odd one. Weigh X against the anyone coin used in initial weighing.<br />o If both are equal, there is some error.<br />o If X is heavy, X is the odd coin and is heavier.<br />o If X is light, X is the odd coin and is lighter. </span>Sumedhhttp://www.blogger.com/profile/11533458660230230361noreply@blogger.com0tag:blogger.com,1999:blog-2267127033347614408.post-29570309562845920462009-08-23T22:24:00.000-07:002009-08-23T22:24:00.605-07:00ow many zeroes will be needed?<span style="font-size:85%;">Puzzle:<br /><br />A certain street has 1000 buildings.

On some day, X lent tractors to Y and Z as many as they had. After a month Y gave as many tractors to X and Z as many as they have. After a month Z did the same thing. At the end of this transaction each one of them had 24.<br /><br />Find the tractors each originally had?<br /><br />Answer:<br /><br />One way to solve it is by making 3 equations and solve them simultaneously. But there is rather easier way to solve it using Backtracing.<br /><br />It's given that at the end, each had 24 tractors (24, 24, 24) i.e. after Z gave tractors to X & Y as many as they had. It means that after getting tractors from Z their tractors got doubled. So before Z gave them tractors, they had 12 tractors each and Z had 48 tractors. (12, 12, 48)<br /><br />Similarly, before Y gave tractors to X & Z, they had 6 & 24 tractors respectively and Y had 42 tractors i.e. (6, 42, 24)<br /><br />Again, before X gave tractors to Y & Z, they had 21 & 12 tractors respectively and X had 39 tractors i.e. (39, 21, 12)<br /><br />Hence, initially X had 39 tractors, Y had 21 tractors and Z had 12 tractors.</span>Sumedhhttp://www.blogger.com/profile/11533458660230230361noreply@blogger.com0tag:blogger.com,1999:blog-2267127033347614408.post-41189367028693989872009-08-21T22:22:00.000-07:002009-08-21T22:22:00.149-07:00RelationShip puzzle 2<span style="font-size:85%;">Puzzle:<br /><br />Three men - Sam, Cam and Laurie - are married to Carrie, Billy and Tina, but not necessarily in the same order.<br />Sam's wife and Billy's Husband play Carrie and Tina's husband at bridge.

Thus, Sam is married to Tina.<br /><br />As Cam does not play bridge, Billy's husband must be Laurie.<br /><br />Hence, Carrie is married to Cam.</span>Sumedhhttp://www.blogger.com/profile/11533458660230230361noreply@blogger.com0tag:blogger.com,1999:blog-2267127033347614408.post-8278096411883908522009-08-20T22:21:00.000-07:002009-08-20T22:21:00.279-07:00Relationship problem<span style="font-family:trebuchet ms;font-size:85%;">Puzzle:<br />One of Mr. Bajaj, his wife, their son and Mr. Bajaj's mother is an Engineer and another is a Doctor.<br /> If the Doctor is a male, then the Engineer is a male.<br /> If the Engineer is younger than the Doctor, then the Engineer and the Doctor are not blood relatives.<br /> If the Engineer is a female, then she and the Doctor are blood relatives.<br />Can you tell who is the Doctor and the Engineer?<br /><br />Answer:<br /><br />Mr. Bajaj is the Engineer and either his wife or his son is the Doctor.<br /><br />Mr. Bajaj's wife and mother are not blood relatives. So from 3, if the Engineer is a female, the Doctor is a male. But from 1, if the Doctor is a male, then the Engineer is a male. Thus, there is a contradiction, if the Engineer is a female. Hence, either Mr. Bajaj or his son is the Engineer.<br /><br />Mr. Bajaj's son is the youngest of all four and is blood relative of each of them. So from 2, Mr. Bajaj's son is not the Engineer. Hence, Mr. Bajaj is the Engineer.<br /><br />Now from 2, Mr. Bajaj's mother can not be the Doctor. So the Doctor is either his wife or his son .

The last person in the platoon wants to give a letter to the first person leading the platoon. So while the platoon is marching he runs ahead, reaches the first person and hands over the letter to him and without stopping he runs and comes back to his original position.<br /><br />In the mean time the whole platoon has moved ahead by 50m.<br /><br />The question is how much distance did the last person cover in that time. Assuming that he ran the whole distance with uniform speed.<br />Submitted<br /><br />Answer:<br /><br />The last person covered 120.71 meters.<br /><br />It is given that the platoon and the last person moved with uniform speed. Also, they both moved for the identical amount of time. Hence, the ratio of the distance they covered - while person moving forward and backword - are equal.<br /><br />Let's assume that when the last person reached the first person, the platoon moved X meters forward.<br />Thus, while moving forward the last person moved (50+X) meters whereas the platoon moved X meters.<br />Similarly, while moving back the last person moved [50-(50-X)] X meters whereas the platoon moved (50-X) meters.<br /><br />Now, as the ratios are equal,<br />(50+X)/X = X/(50-X)<br />(50+X)*(50-X) = X*X<br /><br />Solving, X=35.355 meters<br /><br />Thus, total distance covered by the last person<br />= (50+X) + X<br />= 2*X + 50<br />= 2*(35.355) + 50<br />= 120.71 meters<br /><br /><br />Note that at first glance, one might think that the total distance covered by the last person is 100 meters, as he ran the total lenght of the platoon (50 meters) twice. TRUE, but that's the relative distance covered by the last person i.e. assuming that the platoon is stationary.<br /></span>Sumedhhttp://www.blogger.com/profile/11533458660230230361noreply@blogger.com0tag:blogger.com,1999:blog-2267127033347614408.post-73651660916221286272009-08-17T04:52:00.000-07:002009-08-16T21:22:50.559-07:00Puzzle 1: Bullets problem<span style="font-size:85%;">Three friends divided some bullets equally. After all of them shot 4 bullets the total number of bullets remaining is equal to the bullets each had after division. Find the original number divided.<br /><br />Answer: 18<br /><br />Explanation:<br /><br />Assume that initial there were 3*X bullets.<br />So they got X bullets each after division.<br />All of them shot 4 bullets. So now they have (X - 4) bullets each.<br />But it is given that,after they shot 4 bullets each, total number of bullets remaining is equal to the bullets each had after division i.e. X<br /><br />Therefore, the equation is<br />3 * (X - 4) = X<br />3 * X - 12 = X<br />2 * X = 12<br />X = 6<br />Therefore the total bullets before division is = 3 * X =

<br />
<br />> each contain upto eight syllables, although none of the four
<br />> names
<br />
<br />> contain the same number. Two of the names contain no vowel
<br />> sounds; one
<br />
<br />> contains one vowel sound; and one contains two vowel sounds.
<br />>
<br />> From the Guide's statements below, determine the number of
<br />> syllables
<br />
<br />> and vowel sounds in each of the four Walkie Talkie names :
<br />>
<br />> i) The one whose name contains two vowel sounds is not A.
<br />> ii) C's name does not contain more than one vowel sound or
<br />> fewer than
<br />
<br />> seven syllables.
<br />> iii)The name with seven syllables does not contain exactly one
<br />> vowel
<br />
<br />> sound.
<br />> iv) B and C do not have names with the same number of vowel
<br />> sounds.
<br />
<br />> v) Neither the name with five syllables nor the name with
<br />> seven syllables
<br />
<br />> contains more than one vowel sound.
<br />> vi) Neither the name with six syllables, nor the B's name,

He collected boxes from various people in his local village and each box was labelled in Roman Numerals with the number of cakes in the box. By the time the errand boy had collected the last box, he was quite hungry, and really needed to eat at least one cake. Luckily the last box was marked with an underlined XI, meaning there were 11 cakes in it. He had the brain wave of turning the box around and underlining the number again to give the impression there were IX, that is 9 cakes. However, after eating the 2 cakes, he was still hungry. How can he change the number shown on the box again and eat more cakes?<br /><br /><h3 class="smller">answer</h3> <div class="para"> He could add an S to the IX to give the impression there were supposed to be 6 cakes in the box, thus eating 5 cakes in total. </div>Sumedhhttp://www.blogger.com/profile/11533458660230230361noreply@blogger.com0tag:blogger.com,1999:blog-2267127033347614408.post-15662858047713091062008-08-04T18:32:00.001-07:002008-12-23T21:42:41.354-08:00Crossing the Bridge<h3 class="smller"><br /></h3> <div class="para"> <b>Four people are on one side of a bridge that they need to cross. It is dark, there are holes in the bridge surface, and they only have one flashlight which must travel with them as they cross.

On the first day, he has his students perform an odd opening day ceremony:<br /><br />There are one thousand lockers and one thousand students in the school. The principal asks the first student to go to every locker and open it. Then he has the second student go to every second locker and close it.The third goes to every third locker and, if it is closed, he opens it, and if it is open,he closes it.The fourth student does this to every fourth locker, and so on. After the process is completed with the thousandth student, how many lockers are open?<br /><br />Answer;<br /><br /></b>open lockers are perfect squares 1, 4, 9, 16, 25........ they are the only numbers divisible by an odd number of whole numbers.<br />every factor other than the number's square root is paired up with another.<br />so these lockers will be "changed" an odd number of times.<br />which means they will be left open.<br />All the other numbers are divisible by an even number of factors and will consequently end up closed.<br /><br />the number of open lockers = the number of perfect squares less than or equal to 1000.<br />numbers are 1 squared, 2 squared, 3 squared, 4 squared, and so on, up to 31 squared. 32 squared>1000<br />out of range.<br />ans is 31<br /><br />so answer is 31Sumedhhttp://www.blogger.com/profile/11533458660230230361noreply@blogger.com0tag:blogger.com,1999:blog-2267127033347614408.post-27427563303024095222008-08-04T18:28:00.001-07:002008-12-23T21:42:41.354-08:00Microsoft Puzzle"U2" has a concert that starts in 17 minutes and they must all cross a bridge to get there. All four men begin on the same side of the bridge. You must help them across to the other side. It is night. There is one flashlight. A maximum of two people can cross at one time. Any party who crosses, either 1 or 2 people, must have the flashlight with them.<br /><br />The flashlight must be walked back and forth, it cannot be thrown, etc.<br />Each band member walks at a different speed. A pair must walk together at the rate of the slower man's pace:<br /><br />* Bono: - 1 minute to cross<br />* Edge: - 2 minutes to cross<br />* Adam: - 5 minutes to cross<br />* Larry: - 10 minutes to cross<br /><br />For example: if Bono and Larry walk across first, 10 minutes have elapsed when they get to the other side of the bridge. If Larry then returns with the flashlight, a total of 20 minutes have passed and you have failed the mission.<br /><br /><br />Notes: There is no trick behind this. It is the simple movement of resources in the appropriate order. There are two known answers to this problem. This is based on a question that Microsoft gives to all prospective employees.<br /><br />Note: Microsoft expects you to answer this question in under 5 minutes!<br /><br />Answer:<br /><br />* Bono: - 1 minute to cross<br />* Edge: - 2 minutes to cross<br />* Adam: - 5 minutes to cross<br />* Larry: - 10 minutes to cross<br /><br />Bono and Edge Bono comes back ---(2+1)<br />Adam and Larry Edge comes back----(10+2)<br />Edge and Bono over---------------(2)<br /><br /><br />(2+1)+(10+2)+2= 17 mins<br /><br /><br /><br />Microsoft, hire me because it took me less then 3 MIns to solve :)Sumedhhttp://www.blogger.com/profile/11533458660230230361noreply@blogger.com0tag:blogger.com,1999:blog-2267127033347614408.post-10842484321593561902008-08-04T18:27:00.000-07:002008-12-23T21:42:41.354-08:00Prisoners puzzle<b>A prisoner is faced with a decision where he must open one of two doors.<br />Behind each door is either a lady or a tiger.
