  1. Where is the Astronomer?

    My guess is that it looks like daylight, so the astronomer is either at his job, or asleep.

  3. Come Solve the Show

    gioco per il dì di festa: Come Solve the Show | Notiziole di .mau. | Guest

    […] Come Solve the Show, creato da Plexus (ma io l’ho trovato su Smart-Kit) è un “semplice” puzzle. Nulla di troppo complicato, una volta scoperto che i pezzi si ruotano con le frecce (oppure con A e D), però qualche minuto di divertimento te lo dà. (ah, sì: ti salva – immagino via cookie – il punto in cui sei arrivato, quindi puoi anche fermarti un attimo) […]


  4. Balance the scale puzzle

    Super easy to do algebraically.


    g = green ball
    r = red ball
    b = blue ball
    o = orange ball


    Assuming weight remains constant:


    (1st scale) 2g + 2r = 2b


    ? g + r = b


    (2nd scale) 6g + 2r = 4b + o


    ? 4g = 2b + o (remember b = r + g)


    (3rd scale) 5g + r = ?? (will come back to this!)


    So if we substitute our own numbers for g and r we get b, which we can then use to get o.


    so, for (1): g + r = b


    if
    g = 7
    r = 3
    ?
    b = 10


    So now that we have a value for b:


    (2) 4g = 2b + o

    : 4 x 7 = (2 x 10) + o
    28 = 20 + o
    : 28-20 = 20 – 20 + o
    ? 8 = o


    So now we have 4 numbers which fit into the equation.


    Green (g) = 7
    Red (r) = 3
    Blue (b) = 10
    Orange (o) = 8


    So,


    (3) 5g + r = 5 x 7 + 1 x 3
    5g + r = 38


    38/b = 38/10 = 3 remainder 8 **


    8/o = 8/8 = 1



    ? the answer is 3 blue balls and 1 orange ball.


    ** if only blue balls may be used, the answer is 3.80 blue balls (38/10 = 3 8/10)


  5. Monday Morning Warm up

    I think is the 4th one but it is being shown upside down. The + sign must be in the middle since every other is in the middle. Leaving 2,3, or 4. The arrow never makes it past the middle of the box and always faces up. We can only go by the data shown. Going counter-clockwise is presuming that is the pattern and not using the pattern. Hence, the rotated 4th one works.

  14. Simple puzzle will confuse all but the accountants

    moorski | Profile

    Best way to look at it is. While the bill cost 25, there was a “tip” to the waiter for 2. So the bill totaled 27. Each woman paid $9. 9 x 3 = 27. 25 (meal) + 2 (tip) = 27
