1. A bat and a ball cost $1.10 in total. The bat costs $1 more than the ball. How much does the ball cost?

2. If it takes 5 machines 5 minutes to make 5 widgets, how long would it take 100 machines to make 100 widgets?

3. In a lake, there is a patch of lily pads. Every day, the patch doubles in size. If it takes 48 days for the patch to cover the entire lake, how long would it take for the patch to cover half of the lake?

There is legit research behind this test, do open the link until after you answer the questions. I didn't see the 130 number in the link, saw it online so I have no idea if it's a valid number. You'll be surprised at the scores, test taken at various Universities.

Post your answers, I got all three correct..... woohoo

  1. Five cents.
  2. Five minutes.
  3. 47 days.
You sort of gave away the fact that they were trick questions.

Saw this online the other day and did it then.
All three were pretty easy.

Can see how these might trip up some folks. But the answers shouldn't be too hard, for those who have done some problem solving and who just think for a moment.

I got the answers correct (without scrolling down) so I guess that I am smarter than most but I am only as smart as my next stupid decision.

Looked at the linked article but didn't read the whole thing (not smart enough to do that) but looked at the charts and graphs (like reading USA Today) and noted a couple of critical points when it came to the source of the data.

1) The author is an MIT guy and guess which group scored highest? MIT with another high placing group being common folks who just happened to watch July 4th fireworks in Boston.

2) The only group placing lower than Michigan State was University of Toledo..

3) The arrogant scUM placed higher than MSU.

Great way to start a Friday.

Trick questions, huh? In that case ...
1. The bat and ball may not be purchased separately.
2. The widgets are needed to make the additional machines so it will take those first 5 machines 100 minutes before there are enough widgets to make the next 100 machines operational. However, if more machines become operational as soon as a batch of widgets is made (i.e., you have 10 machines making more widgets after the first 5 are made), then it will take 30 minutes before you will have made at least 100 widgets.
3. There is no species of lily pad on earth that can double in size in one day and the nutrients needed for it to do so if it could cannot be contained in any lake (OK, maybe a lake of nutrients). Therefore, this must be taking place in another universe in which our conventional concepts of time and space do not apply. Since we do not know the rotational speed of such a planet, we can't define what a "day" is so one cannot answer such a trick question.

Or maybe I'm overthinking it. Gotta love a bye week.

The second one could be 1 or 5 minutes depending on how you interpret the rate.

Yeah...As I'm reading through all the BS in the original post link, I'm losing patience looking for the answers. Thinking that is the real test! (having done some psych experiments where you do some task and I know they are looking at something other than the "task" being performed)...anyway I lost patience with the link and came here for the answers....Which I aced by the way.

It's actually pretty accurate from my experience. I would bet most of the people who completely buy "the narrative" fall into the 0 or 1 range with some outliers at 2.
 
These all appeared to be simple math word problems to me. Not too difficult to do. Since I am used to “trick” questions because of my college of science education at PSU, I always assume something that appears simple is actually a trick question. The education I received at Penn State gave me permanent paranoia about test questions, sometimes to my detriment as I would spend too much time fretting on how the test writer was trying to trick me.

It was slightly different.

1. A hot dog and a Pitt Football ticket cost $1.10 in total. The hot dog costs $1 more than the Pitt Football ticket. How much does the Pitt Football ticket cost?

2. If it takes 5 HS dropouts 5 minutes to make 5 orders of fries at the O, how long would it take 100 HS dropouts to make 100 orders of fries?

3. In a toxic pond in Oakland, there is a patch of medical waste and used syringes. Every day, the medical waste doubles in size. If it takes 48 days for the medical waste to cover the entire pond, how long would it take for the medical waste to cover half of the pond?

Actually you should change HS dropouts to Pitt grads in #2. Hehe - my sister has 2 degrees from Pitt.
 
I got them all right but I failed to find the answers (except for the first one) in the linked paper. So I guess I failed the reading portion of the exam.

You should have given extra credit for any poster who not only got the answers correct, but shared the mathematical formulas and logic for solving. I'm kinda disappointed that I have to cover for @LionJim.

Question 1:

Equation 1: BAT + BALL = $1.10
Equation 2: BALL + $1 = BAT

After substituting the definition of BAT in equation 2 into equation 1 you end up with:
(BALL +$1) + BALL = $1.10, thus
2*BALL + $1 = $1.10, thus
2*BALL = $1.10 - $1 = $0.10, thus
BALL = $.10/2 = $0.05

Now substituting BALL at $0.05 into Equation 2 above, we end up with BAT = $0.05 + $1 = $1.05
----
I'm really interested to see LionJim show the necessary equations for solving the pond lily problem from the perspective of a person sitting at the pond on Day 2 after having just watched the lily pad double in size overnight, and wondering when the entire pond will be covered. Can he do so without using exponents, square roots or knowing the area of the initial lily pad and pond? Let's see what he comes up with :)

Agree wholeheartedly. They are common sense questions, but showing the math requires true understanding and shows the ability to solve more complex problems.
