    Blue Eyes:

    (source: a web puzzle-page, cut-and-pasted verbatim)

    A group of people with assorted eye colors live on an island. They are all perfect logicians — if a conclusion can be logically deduced, they will do it instantly. No one knows the color of their eyes. Every night at midnight, a ferry stops at the island. Any islanders who have figured out the color of their own eyes then leave the island, and the rest stay. Everyone can see everyone else at all times and keeps a count of the number of people they see with each eye color (excluding themselves), but they cannot otherwise communicate. Everyone on the island knows all the rules in this paragraph.

    On this island there are 100 blue-eyed people, 100 brown-eyed people, and the Guru (she happens to have green eyes). So any given blue-eyed person can see 100 people with brown eyes and 99 people with blue eyes (and one with green), but that does not tell him his own eye color; as far as he knows the totals could be 101 brown and 99 blue. Or 100 brown, 99 blue, and he could have red eyes.

    The Guru is allowed to speak once (let’s say at noon), on one day in all their endless years on the island. Standing before the islanders, she says the following:

    “I can see someone who has blue eyes.”

    Who leaves the island, and on what night?

    There are no mirrors or reflecting surfaces, nothing dumb. It is not a trick question, and the answer is logical. It doesn’t depend on tricky wording or anyone lying or guessing, and it doesn’t involve people doing something silly like creating a sign language or doing genetics. The Guru is not making eye contact with anyone in particular; she’s simply saying “I count at least one blue-eyed person on this island who isn’t me.”

    And lastly, the answer is not “no one leaves.”

    Poison Perfidy:

    (source: another cut-and-pasted web puzzle page)

    In a far away land, it was known that if you drank poison, the only way to save yourself is to drink a stronger poison, which neutralizes the weaker poison. The king that ruled the land wanted to make sure that he possessed the strongest poison in the kingdom, in order to ensure his survival, in any situation. So the king called the kingdom’s pharmacist and the kingdom’s treasurer, he gave each a week to make the strongest poison. Then, each would drink the other one’s poison, then his own, and the one that will survive, will be the one that had the stronger poison.

    The pharmacist went straight to work, but the treasurer knew he had no chance, for the pharmacist was much more experienced in this field, so instead, he made up a plan to survive and make sure the pharmacist dies. On the last day the pharmacist suddenly realized that the treasurer would know he had no chance, so he must have a plan. After a little thought, the pharmacist realized what the treasurer’s plan must be, and he concocted a counter plan, to make sure he survives and the treasurer dies. When the time came, the king summoned both of them. They drank the poisons as planned, and the treasurer died, the pharmacist survived, and the king didn’t get what he wanted.

    What exactly happened there?

    #1068577

    How about:

    The treasurer brought a poison. The pharmacist brought water (or other non-toxic solution) and drank an extremely weak poison before the meeting. When they switched after drinking their own,the treasurer drank water which could not counteract the poison he brought but the pharmacist had drunk the weak poison which counteracted the one he had taken beforehand.

    did i get this one right?

    #1068578

    havesomeseichel-

    You’re headed in the right direction, but remember – each drank the other’s poison first, then their own.

    (Welcome back – hope everything’s been OK.)

    #1068579

    thanks for noticing that I have not been around. I kind of gave up on the CR for several months now…. Life has been pretty crazy for me. one thing and then another- i just cant handle life sometimes. I needed some laughs and maybe catch a riddle or two so I came on to the CR.

    Ok, since they each drank the other’s first here is a play by play. T stands for Treasurer and P stands for pharmacist.

    T knew that P was better at this so he came up with a brilliant plan. he would take some weak before he got there and brought along water to give to the P. that way the P would drink the water and then his really strong poison and die. The P, being really smart (he had to be to take orgo-organic chemistry which is needed to be a pharm.), decided to bring water along as his “poison”. That way the T would die from the poison he had taken right before the meeting. the king lost out because his treasurer dies and each one only brought water and no poison.

    Is this right?

    havesomeseichel, I am not a frequent poster on this thread (I gave up a while ago) but I do read. I give you a bracha that everything that has not yet, work itself out, quickly and easily. Life can be (often is) tough, but remember that Hashem is holding your hand and he has a plan even if it makes no sense to you now. If you’re looking for a laugh, I will put my joke of the day gabbai title to good use. Check out the humor thread. (and remember to smile!)

    aussieboy-

    When I repeated this puzzle at a kiddush on Shabbos, someone said that they’d heard it about a Jewish advisor (or something along those lines).

    In their version, the advisor could only create the weak poison and substituted water, while the chemist didn’t figure out the advisor’s plan and died.

    I only saw it on a logic puzzle thread.

    #1068586

    ok, i am working on the blue eyes one….

    so if I see 99 people with blue eyes that night, i dont know if I have blue eyes or not. so I wait to see if anyone else leaves. since no one else leaves (they dont know if they have blue eyes either and they are all waiting to see if anyone leaves). So really all the blue eyed people (100) leave at the same time cuz they realize that no one else left yet that they must have blue eyes. the brown eyed people dont leave cuz they each see 100 people with blue eyes.

    so what day did they leave? the 99th day? since two people would look at each other on the first day and not see anyone leave, that they are both blue eyed. then look on the third day at three people and if no one leaves after two days then they have blue eyes. so on the 99th day and no one has left- they have blue eyes and know that there are 100 people there with blue eyes and they all left together.

    am i heading on the right track?

    here are some riddles of my own (sorry if they are repeats, didnt look through all the pages to find out yet)

    Four men were in a boat on the lake. The boat turns over, and all four men sink to the bottom of the lake, yet not a single man got wet! Why?

    What can run but never walks, has a mouth but never talks, has a head but never weeps, has a bed but never sleeps?

    Whoever makes it, tells it not. Whoever takes it, knows it not. And whoever knows it wants it not.

    What gets wetter the more it dries?

    1) They were all married? (There’s actually a RL scientific possibility that no water would get in the boat, if it capsized perfectly and the air is not allowed to escape).

    2) A river

    3) Counterfeit money

    4) A towel

    havesomeseichel-

    On the 100th night all the blue-eyed people leave.

    This logic works until on the 100th night, when all blue-eyed people would leave.

    #1068592

    havesomeseichel-

    “Four men were in a boat on the lake. The boat turns over, and all four men sink to the bottom of the lake, yet not a single man got wet! Why?”

    a) all four got wet

    b) they were already wet from swimming / getting caught in the rain

    c) they were wearing diving suits

    d) they were trapped in the boat as it sank (unfortunately this really happened to many sailors at Pearl Harbor)

    “What can run but never walks, has a mouth but never talks, has a head but never weeps, has a bed but never sleeps?”

    A hyperactive 18-month old (runs around all the time, doesn’t talk yet, screams [weep has a more genteel connotation], and it sure seems like he never sleeps).

    #1068593

    Mazel Tov squeak! you got them all right! no single man got wet cuz they were all married!

    ICOT- love your answer to the river one tho!

    ok, got to find harder ones next time!

    there are 2 opinions on the amount of lashes one says 39 and one says 40:

    when would they agree to give the same amount?

    when the guy being lashed had done 40 aveirot which deserve lashes.the 40th is that he gave someone 40 lashes.

    so the opinion which says you do 39 its 39 times 40(the fortieth being for adding a lash)

    the opinionwhich says 40 does not count the 40th aveirot so its 40 times 39.

    Oy now is that not gevaldik?

    Why is someone who does so many aveiros sitting on a Bais Din giving lashes?

    Hey! welcome back, doc!

    #1068597

    dr pepper- he gave lashes to 40 people (or would it be 39?) cuz then he wouldnt have done aveiros except giving it to others… or am i misunderstanding that whole post?

    I’m also Dr. Pepper but not the one you are thinking about. I’m substituting for my husband for the time being. (I’ll let him know you miss him.)

    I just consulted my husband (or “The Doc” as he likes to be referred to as) and he explained the scenario in somewhat more detail.

    The mishna in Makkos Perek Gimmel Mishna Yud brings down the different opinions on the number of lashes on receives- either 39 or 40. When will it not make a difference?- when the messenger of Bais Din who is administering the lashes already deserves 39 sets of makkos for prior aveiros performed. While he is giving lashes to another person the counter counts to 39 and gives him a warning not to whip him anymore. He continues with one more whip.

    So if the correct amount of lashes is 40 then he did nothing wrong and he is still liable for 39 sets of 40 lashes (1,560 ouch!). If the correct amount is 39 then he is now liable for an extra set for wounding someone, and now he is liable for 40 sets of 39 lashes (also 1,560).

    My question above “Why is someone who does so many aveiros sitting on a Bais Din giving lashes?”- the mishna in Sanhedrin, perek tes mishna hay says that if one is liable for two sets of makkos he gets put into a cell and fed barley- not appointed to bais din to administer makkos?

    Long distance cost 1 cent per minute with 3 different carriers. The only difference is Carrier A bills in 1-second increments; Carrier B bills in 6-second increments; and Carrier C bills in 60-second increments.

    Which carrier is the lease costly, and by how much over the other 2 competitors?

    Assume Carrier B suddenly implements a 30-second minimum (per call) on its 6-second billing. How does this change the math comparing the 3 providers?

    #1068607

    wouldnt carrier A be the cheapest as you pay for what you talked? if you use Carrier B then when you talk 7 minutes, you get charged for 2 segments or 12 seconds.

    if you talk for a 61 seconds:

    Carrier A costs 61 cents

    Carrier B costs 66 cents

    Carrier C costs 120 cents

    #1068608
    chaverim
    Member

    hss: ?? If you talk for 7 minutes with Carrier B, you get charged for 420 seconds (70 increments of 6-seconds each) for a total of $0.07.

    Obviously Carrier A will always be cheapest (since they all have the same price, while Carrier A has the smallest increments). You need to demonstrate how much the difference is between carriers and how you arrived at your conclusion.

    Also, all carriers bill calls in fractions (i.e. no rounding).

    I meant 7 seconds… sorry. typo..

    hss: The main point of the riddle is to demonstrate how much of a difference it is between the carriers, and how you did your math.

    I should add that the customers average call length is random, meaning call usage could be any random amount of seconds/minutes. (There is no preponderance of short or long calls).

    Its poshut A is cheaper than B which is cheaper than C. The question is how much percent is the average billed savings.

    (Are the math wizards here stumped?)
