Here’s the World’s Shortest IQ Test: Just Three Questions . . . and 83% of People Fail

The world’s shortest IQ test is spreading around online right now.

It’s only three questions long . . . but only 17% of people get all of them right.

That means 83% of people fail. (ok I didn’t even do this math- it’s in the original post so I’m pretty sure already I’m going to fail.

But here we go:

The three questions . . .

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

2. It takes five machines five minutes to make five widgets. How long would it take 100 machines to make 100 widgets?

3. There’s 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 will it take to cover half of the lake?
