Three questions separate you from being of average intelligence and full-blown brainiac – but are they as easy as they seem?

The Cognitive Reflection Test has been hailed as the world’s shortest IQ test as it features just three questions.

1. A bat and a ball cost $1.10 in total. The bat costs $1.00 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?

Now that you’ve had a chance at the questions, you probably answered $.10 for question 1, 100 minutes for question 2 and 24 days for question 3.

If you did, you are wrong.

Here are the correct answers to the test:

Got them all!

The key is realizing they are "trick questions" and need to be read carefully and logically. I almost FUBARED the first one, but caught myself.

I also think I've seen these before, hut it's been a while.

Too easy for a logical mind (assuming I got these easy trick questions right).

This can't be true. I got all of them correct and if I were a brainiac, why ain't I be rich?

It isn't true. You know who I know? The article is from here:

It's to make people who read the NY Post think they are actually smart. At this point, I'm starting to wonder if people who continue to read corporate media if they are even human, no offense to anybody that is reading the NY Post.

Got the first one wrong, the other two seemed pretty easy though. Is there a time limit or something? Otherwise seems like it wouldn't measure much.

Always check your answer. Math isn't always obvious but it's always logical.
