    I posted it without knowing the answer. When I checked the answer it was stupid. Made no sense. I'm still looking.

    I never got that riddle. I'm relieved to hear you say the answer was stupid. But I was ready to tackle it again!


    Looking forward to the next offering!

    Three people check into a hotel. They pay $30 to the manager and go to their room. The manager finds out that the room rate is $25 and gives the bellboy $5 to return to the guests. On the way to the room the bellboy reasons that $5 would be difficult to split among three people so he pockets $2 and gives $1 to each person. Now each person paid $10 and got back $1. So they paid $9 each, totaling $27. The bellboy has another $2, adding up to $29.
    Where is the remaining dollar?
    Thanks from Amelia

    each person owed 8.33.

    the bell hop gave the guest 1 dollar of the 1.66 owed each...making the total 9.33. the bell hop kept the .66 from each

    That's a fun one. I solve it with a pie chart to help me keep track of where all the dollars are.


    Reminds me of quick change artists confusing clerks at fast food joints.

    Can you figure it out what the final answer is in both equations?

    Dude,. you should plug it into the game theory formula you posted one time. That would solve it!

    Yes, 40, not too fucking difficult even for folks without PhD's

    I think 96.

    8 X 11= 88 + 8

    Examples 2+5 and 3+6 suggest that the 2nd number is multiplied by the first number, then added to the first number

    That's an elegant solution. A shortcut from how I did it. Nice.

    This kind of pattern solving is interesting as it tells us a lot about how our brains work.

    The puzzle is displayed as linear mathematical problems. Working them as they are laid out, horizontally, looking for the "trick", will lead you to the 96 answer. Looking at the entire puzzle as a whole and viewing it from the perspective that it's a grid and not just horizontal problems will lead you to the 40 answer.

    I think that's the actual cool part. Not that there are two different answers but how our brains lead us to find the two different answers.
    Thanks from Chief
