    Totally agree with DeeGee here. If the first click STARTS the timer, Buzzy is the fastest clicker with 19 clicks in 20 seconds (19/20), followed by Emily with 9/10 then by Anthony with 4/5. To better illustrate we need to consider the time between clicks and not the number of clicks in a period of time. C = Click (no time) T = Time period For Anthony, he's clicking by following the series below C T C T C T C T C in 5 seconds 4T = 5 seconds => T = 1.25 Anthony will then complete 40 clicks in 39xT => 39x1.25 = 48.75 seconds Emily: C T C T C T C T C T C T C T C T C T C

    I tried this as a test!! I just threw the phone guide from the 3rd floor of my building and all 527 pages landed in a perfect pile!! Amazing, I wonder if people would actually pay money to see this incredible show! I think I can get a job as a university professor now easy

    What a long (and complicated) thread to read... So here's my contribution to this subject. Going back to the original OP, the 2 players are masters of logic (and both love beer). They want to maximize the number of beers, they don't look to get more than each other. The word "sucker" will not affect their judgements either (emotional triggers do not affect masters of logic). In that case defecting would be stupid, illogical and an EMOTIONAL decision. That being said, Masters of logic would always cooperate. Defecting even once is an emotional decision Now I realize that, since this

    Is the second condition (divisible by 9) needed in this case? It goes without saying, doesn't it?

    I thought they arrested the murdereD as by the OP.

    I hope I didn't make any mistakes rushing into this...

    Rule #1: Never be the first to go for the average in your counter offer!!!! In the previous solutions, it was assumed that the seller would start by asking for $75 In my opinion, the seller being more professional and experienced would have waited untill Sean agreed on paying $75, then he would ask for the new average. superprismatic was right on both accounts I think.

    This OP did produce a single solution! This made me think of a twist: Would we always have one single solution had K Sengupta chose any other triplet of 3 jobless candidates in that interiew? If not, what is(are) the triplet(s) that would give more than one possible solution in that case? Remember, the right sequence is fixed in the spoiler above The jobless candidates have 2 or less right answers I hope it's ok with K Sengupta that I posted this. I hope you find it interesting to prove/disprove. At least, it was for me!

    I've been sitting here reading all these posts about ogre being stupid and I've had it! I think you all owe my wife an apology! In her own words: "Omf kuf tuug gsut gout!" You guys should be ashamed of yourselves.

    I only have one issue with these solutions, Since there is no information about my rowing speed in the OP (usually much less then my running speed), the proposed solutions may leave me running in circles, never getting to shore!! A very tight giant spiral will be my final trajectory. In fact, there must be some minimum rowing speed where I can reach the shore with the ogre at least a feet away from me, so that I can outrun it. This would make a nice puzzle!

    I think I agree... And the Brain wins again... What a shocker!

    I'm not sure why but... Although I learned not to use my instincts in probabilities. But this feels like the ultimate battle between Emotions & Machine (Computer code) And the winner is ... again.
