Great puzzle! I figured it out in the shower tonight. Plenty of paint! It is a min max problem like I thought, but you don't need calculus.
J_Sim is not a bozo by any stretch of the imagination. eom
bagwa-john, J_Sim signed up on I-Hub so he's now a member, and you are correct in your assumption. Before I had come up with my response, I had actually considered the answer he gave me privately. I made it more complicated than it had to be. Hint hint.
Look for the simple solution.
Come to think of it though, he deserves to be spanked since I had asked him not to tell me the answer, but it will be fun watching the rest of you try and figure it out.
baga:
You are overlooking one thing. The bozo that brought it up may not have a HS edgeecation and it's all a bunch of crap!

I think there is a way to use a min-max application from calculus, but somehow I think Plato could have figured it out using an elegant geometric illustration. I think I'll go that direction with it. I think there is a principle we need involving concentric circles and the relationships of one's area to the other. I'm up to speed with all my geometry and trig, but this one involves thinking outside the box. It wouldn't be in a brain test if it required calculus.
Look for the simple solution. imo. still working on it.
Uh-oh, I just realized two things.....
1) The diagram may not have been brought into the store, and....
2)......even if it was, the circles may not have been drawn to scale.
Back to the drawing board! Pun intended.
It worked okay for 4 other people on here so it must be something about your computer setup. Try it on a different computer if available.
J_Sim...If there's any confusion about what I said here:
Then the areas of the outer and inner circles can be determined (using the 20' markings to scale)....or however that should be worded....with pi r squared as the equation.
...I meant that a straight edge rule could be constructed using the 20' markings to determine exactly how long the radius of the larger circle is. The same ruler could be used to figure out the smaller circle's radius.
That solution would work, but if the intended answer is different, please let me know....but don't say it on the board. Others might have fun figuring out a better solution than the one I have.
------------------
Edit: I just realized that you aren't a member so you can't send a private message. Oh well....all the more reason I hope someone else comes up with something better.....pronto!
Hey, you couldn't answer any of them which means you got a big fat 0. LOL!
Something's not right, that link does nothing but bring up a blue flash player square and nothing else.
So I guess I get them all right by default. LOL
OK, it's morning and the only way I can think to do it is to first find the midpoint of the circles which can be done a number of ways, the easiest being to either:
1) cut out the large circle (with the smaller one intact), and fold it in half, top to bottom and then once again using the straight edge of the folded circle to fold again.
Or
2) draw a box around the circle that touches all four points north/south/east/west using the edges of the paper as a guide....and then draw an X to divide the box.
----------------------
Then the areas of the outer and inner circles can be determined (using the 20' markings to scale)....or however that should be worded....with pi r squared as the equation.
------------------------------
Finally, subtract the smaller circle's area from the larger circle's area.
---------------------------
I'll bet there's an easier way, but I can't think of it.
---------------------------
And the final question would be, are there two coats of deck paint required?
If you know you're looking for a man, its quick. just looking at the beans without a template takes a while.
I took that test at work. I missed three. I think I'm going to like this board!
J_Sim, Your puzzle is driving me nuts....trying to figure it out this late at night. I'd suggest that he buy a gallon of latex paint and mix it with some extra water beforehand....just in case. LOL!
Don't give the answer!
Tomorrow is another day.
18 but can't believe I missed the eight-sided stop sign.
Speaking of merry-go-rounds running counter-clockwise, it reminded me of a classic think test.
A man comes into a paint store wanting to know if a gallon of deck paint (400 sq ft of coverage) would paint the floor of his merry-go-round. The only measurement he brings is that from one side to the other barely touching the inner wheelhouse being 20 feet (see diagram).
The man behind the counter isn't sure and wishes that his customer would have measured around the inner wheelhouse and the distance straight out from the wheelhouse to the edge. Can you help him figure it out or does he need a second measurement?
J Sim
I got 15 out of 25.
It says that 7 is average, but there is no possible way that could be true. Even if you threw a dart, you would average 8.333 and considering some of the third choices were nothing but a lark, if you threw a dart at the reasonable options you would probably get around 10 (on average).
I don't think I did all that well and yet someone would have had to have a zero for the two of us to average 7 ish.
Len
Same as me. I got 17 also.
17 right lol
1, 4, 3, 11, 15, ?

You may be correct, taking care of a 1 year old can do that to you!
maybe it means you are in touch with your feminine side, lol, just kidding.
1, 4, 3, 11, 15, ?
I just made this one up.
I hope I calculated correctly. :^)
(I'm pretty sure I did, but it is 4:35 AM)
Lentinman - looking at the image again, I concede that's the one that the question is referring to.
But I'd consider any other answer to be valid as well, it's truly in the eye and imagination of the beholder.
Aiming:
That's the one I saw. I spent 7 seconds looking for something bigger. I abandoned that and instantly saw the single bean.
Len
Yep, I didn't see that face until I saw your earlier post, but this is like a Rorschach test, anyone can see anything and it's not wrong.
I'd almost bet that the other people that saw a face didn't see the same one you or I saw.
It's not more than ONE bean that shows the face.
Look at the 7 O'clock position and you will see ONE been with a balding head, two eyes, and a nose!
Oh, geeeez, I wanted to read a few more quizzes....and here's the answer.
I can think of two answers:
1) If you use Roman Numerals, and the "I" tips over to the right, and onto the V's midpoint (lying horizontally) it kind of slices it in half. Or take the I and move it directly to the right, and halfway 'into' the V.
2) An even better one would be taking the word FIVE and removing half of it (the letters F and E which would leave the roman numeral IV (4).
Time for bed.
It would be interesting to know which face each person is seeing, I could see any number of bean combos that could make a face with a bit of imagination.
Any given pair of beans forms a pair of eyes.
I'm guessing most people are considering the small square "hole" in the middle of the image to be the mouth of the face.
He looks like a pervert at 7PM!
I saw him instantly! Almost! About 4-5 seconds.
Maybe he knows you?
I saw him looking up at me immediatey and he scared me, what does that mean?
Dan:
About 6 seconds.
Len
Doctors have concluded that, if you find the man in 3 seconds, then the
Right half of your brain is better developed than most people.
If you find the man between 3 seconds and one minute, then your right
Half of the brain is developed normally.
If you find the man between one minute and 3 minutes, then the right
Half of your brain is functioning slowly and you need to Eat more
protein.
If you have not found the man after 3 minutes, the right half of your
Brain is a mess, and the only advice is to look for more of these types
of exercises to make that part of the brain stronger.
The man is really there. Keep looking!
Len:
it was late. My fingers were tired, lol.
Lady:
"of course it is! a nickel, the dog cost 1.50"
Didn't you mean 1.05 not 1.50?
Len
Lady:
Another answer is...
... When you subtract three from each of them.
Len
Very tricky, I googled it so I'll refrain from answering.
But tricky!
ETA: I see someone got it. Great out of the box thinking.
If you have a dime and a dollar ($1.10)
and the dog costs a dollar more than the collar...
then the collar could have cost anywhere from .01 to .10 (assuming no tax)
So my answer is .01 to .10
I had the lucky daisy on my side!
Go get'em!!! Whahoooo! correct: F(IV)E
Roman numerals iv
five
Fourth question still up for grabs:

When is four half of five?
couldn't get that one past you, Len. Nice job.
Why is it against the law for a man living in North Carolina to be buried in South Carolina?
Because he is still living
of course it is! a nickel, the dog cost 1.50
