Here's an easy IQ test for you:

People have been stewing over the correct answer to a coffee-themed puzzle. A Twitter user shared the logic quiz, in which coffee is poured into a network of pipes leading to four different cups.
You have to figure out which of the cups will receive coffee first:

Scroll down for the answer:

A closer look at the pipes shows that the coffee will actually end up in only one cup ― number 5. That’s because the pathways to the other three cups are all sealed off.

Here's an IQ test with only three questions:

Here Are the Questions

1. The Ball & Bat Problem:
A bat and a ball together cost $1.10. The bat costs $1 more than the ball. How much does the ball cost?

2. The Widget-Making Machine Problem:
If it takes 5 machines 5 minutes to make 5 widgets, how long would it take 100 machines to make 100 widgets?

3. The Lily Pad Patch Problem:
There is a patch of lily pads in a lake. 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 the lake?
Scroll down to read the answers to the questions.

Here Are the Answers

1. The ball costs 5 cents. You probably guessed 10 cents, didn't you? No judgment. A ball that costs 5 cents plus a bat that costs $1.05 will set you back $1.10. And $1.05 is exactly $1 more expensive than 5 cents. A Princeton study found that people who answered 10 cents were significantly less patient than those who got it correct.
2. It would take 100 machines 5 minutes to make 100 widgets. Your gut might tell you the answer is 100 minutes. From the question, we know that it takes 5 minutes for 1 machine to make 1 widget. Thus, it would take 5 minutes for 100 machines to make 100 widgets. (Check out a similar, if not more difficult problem, here.)
3. The lily pads would cover half the lake in 47 days. You might have guessed 24 days. It seems intuitive to halve the number of days because you're halving the size of the lily pad patch. But if the area of the lake covered in lily pads doubles every day, it would only take one day for it to go from being half covered to fully covered. Take one day away from 48 days and you're left with 47.

In which case:





  1. I got the machine making widgets question right. Do I get a gold star?

    1. No, you get a free widget--watch your mail!!

  2. I am brighter than I realised. I didn't get the dollar more question right, though I knew my answer was wrong. I got all the others though.

    1. If you knew it was wrong, that was right!!

  3. I have a headache now. Thank you:)

  4. Missed the coffee one because I didn't see the blocks--duh! Too trusting, I say. Lost trust, woke up my brain, and got all three of the next ones--LOL! Love the cartoons. Have a great weekend, Fran. :)

  5. Apparently I am still stupid.

  6. Well it is official, I am impatient and poor with detail. That's OK, my dog looks up to me.

  7. After a rocky start, missing the coffee question because I did not pay attention to the blocked details...I got the other three right.

    I justify my mistake with the fact that I don't drink coffee, so I was not really invested in the answer...Who knew that I loved bats and balls and widgets and lily pads so much?

  8. I hate questions like that. They make me feel stupid. Oh, well. My IQ is higher than Forrest Gump's.


  9. Got the first one wrong. I said none would fill, because it looked like cola not coffee to me. Just proves what others have always said: my IQ is the square root of -1

  10. Well, i'm with the chicken, those tests are flawed. And i clean houses instead of sitting at a desk for a reason!


Your comments make my day, which shows you how boring my life has become.
