    Ok since the first lot gained a fair bit of interest, here are ten more. Best of luck!

    1. What is the deepest lake in the world?

    2. What was the name of Augusta Ada King's first Grandchild?

    3. With current technology, how long would it take on average to travel to the planet Neptune?

    4. How many noses does an ant have?

    5. Who was the very first manager of Watford FC?

    6. What does the term "Turing Tested" mean?

    7. What does the following formula calculate, if 'f' is the result and 'n' is the number to be calculated?

    f = n * n * n * ^2pwr / n1

    8. How many colours of our spectrum can dogs see?

    9. What was the main reason Sega dropped out of the Video Game Console market?


    10. A train pulls in at a station. It has a total 16 passengers on board.
    When it reaches it's first stop, half that number get off and twice the number get on who first boarded the train when it began it's journey.
    When it reaches it's second stop, a quarter of the number of the original paying passengers get off and double that of the first stop get on.

    A train also has a gaurd, a driver and a conductor on board.

    When it reaches it's final stop all of the passengers get off the train including the three mentioned above.

    How many passengers were on board the train when it arrived at the final stop?

    1. Sure it’s the one in Zambia
    4. No nose
    6. Not sure officially but it’s a way of testing a computers intelligence
    8. Yellow and blue - why all the balls I throw are in that colour

    10. 16 passengers + 3 staff -8 + 38 -4+32= 77

    Turing Test means the computer's answers are indistinguishable from a human's ie: with a chat bot you couldnt tell if talking to a computer or a person

    6 - the Turing test was invented by Alan/Allan ? as a way of testing if an AI system had reached human intelligence. Something along the lines that any typed question from any person gets a response from the AI that can't be differentiated as human or AI passes the test.

    Although many AI people believe this test is no longer pertinent and better ones have been created.

    10 -Could prob work this out but can't be bothered.

    Think your 2nd 32 should be 64, but could be wrong!

    No 10.

    Driver and crew don't count as passengers so;
    16 - 8 + (16+3)*2 - 4 + 8*2 = 58 or
    16 - 8 + (16+3)*2 - 4 + (16+3)*2*2 = 118

    Depending on whether "...a quarter of the number of the original paying passengers get off and double that of the first stop get on..." means double the number that got off at first stop, or got on at the first stop, it's not clear.

    "who first boarded the train when it began it's journey" must include the driver and crew who would also have boarded the train (and who otherwise don't count as not "passengers") so the 16 and 32 must be 19 and 38 surely ?

    It’s all a bit ambiguous, depends how/if you include the crew in the calculations

    1. -- correct
    2. -- correct - Judith Blunt-lytton, daughter of Ada's first born, Anne Blunt (sic King)
    3. -- correct - it's an average but 12, but other factors do come into play and your answer was in that field.
    4 -- correct - they use their antennae for sense
    5 --
    6 -- correct - Alan Turing test's if an AI can achieve human intellegence, by 100% modeling how a human would respond to a given stimulas.
    7 --
    8 -- correct - most dog toys are yellow and blue.
    9 -- correct - there are other reasons with one big one Sega messing up the launch of the Saturn and pricing it $100.00 more than Sony's Original Playstation. Also, the internal structure was rancid.
    10 -- correct - 48 was the answer but i messed up the wording so it's void. Sorry for the mix up.

    Some small hints:

    For question one, the Lake begins the letter B

    10. Doesn’t make sense based on what you’ve said. “When it reaches it's second stop, a quarter of the number of the original payingpassengers get off” but if there were 16 passengers onboard and 3 of those were staff then there would be 13 paying passengers originally.

    Train staff do not pay to board the train, they were on the train before it reached it's first stop. First number of the equation you get is 16 (as they are the people who had to pay), and you just add 3 to the total at the end to account for the staff. I probably could of worded it a bit better to be honest. :(

    Your answer before hand is correct about the dog sight.

    it was your hint above that staff are still passengers that made me confused

    It’s actually fairly straight forward. Passengers exclude staff so 16 passengers at first but 19 “on the train” for later calculations of new passengers based on “the number who were on the train at the start”. You don’t add 3 at the end as the staff aren’t passengers. The only ambiguity was the wording I flagged in the post about 9 above this one which gives the 2 different answers I showed based on how it’s interpreted.

    Trick to it is, the staff are passengers on a moving vehicle, paying passemgers or not, they are still tavelling. If nobody was on the train at all, it would obviously be empty. When the three staff members board the train, they then become passengers of that vehicle. Reason I used the term "paying passengers" is to distinguish them from the three staff members, but the total imcludes all paying passengers left on and the three staff, who all get off leaving the train empty at the end.

    That's probably how I should of worded it. It does have an answer, and it's less than 80.

    The undeniable truth First Team Captain

    Staff on board are not "passengers".
    " A passenger is a person who travels in a vehicle, but does not bear any responsibility for the tasks required for that vehicle to arrive at its destination or otherwise operate the vehicle, and is not a steward" https://www.google.com/search?client=firefox-b-d&q=passengers+definition
    "Passengers" at the start must be 16. "The number who first boarded the train" must be 16+3=19, so your version of the answer is flawed I'm afraid.

    Train Total at start : 0
    Train passengers when gaurd, conductor and driver get on : 3
    Passengers added to train before first stop : 16
    Total Train at First Stop : 19

    First Stop
    Half of that Number get off : 8
    19 - 8 = 8
    Twice the number get on when it first started it's journey : 6
    8 + 6 = 14
    Total Train after First Stop : 14

    Second Stop
    A quarter of the number of the paying passengers get off : 4
    14 - 4 = 10
    And double that of the first stop get on : 38
    Train Total after Second Stop : 48

    Final Destination : 48 leave the train.

    I've confused myself I think, this is how the result is calculated.

    I can see what you intended but;
    1/ your definition of "passengers" is flawed so the numbers are not correct.
    2/ The number on board when it first started it's journey (passengers AND staff) won't be 3, as there will be passengers on the train too.
    A shame as that type of question can be fun to work out.

    Yes I totally agree with you. Next week I'll try to make sure I screw my brain in correctly and test my logic before I post a complex mathematical one. But I take all your comments on board and thank you for pointing out where I went wrong. I will mark this one as answered now. Thanks again Tut. :)

    Sega just made a lot of bad consoles, lost money, made it hard for 3rd parties to make games for them, there were better alternative consoles towards the end such as PS2 and xbox, so they stopped making consoles and now are bad at making games
