Please keep your scroll bar right here, though…as in, don’t scroll down and read anyone’s reply yet. See if you can do it yourself.
Also, don’t use a calculator or Pen/Pencil and paper. It’s easy enough to do in your head.
You start out with 1000.
Add 40.
Add another 1000.
Add 30.
Add another 1000
Add 20.
Add another 1000.
And finally, you add 10.
What number did you get? Reply first by hitting the submit reply at the TOP of this thread,…THEN read your fellow doper’s replies and comments.
It’s more effective if done verbally. You can see four 1000s on the screen, and no other big numbers, so it is painfully obvious it will be just over 4000. When you do the same thing out loud, more people will make the mistake intended by this riddle.
One way to simulate this effect might be with spoilers:
You start out with 1000.[/spoiler]Add 40.Add another 1000.Add 30.Add another 1000Add 20.Add another 1000.[spoiler]And finally, you add 10.
Initially I went 5000. But then I thought, come on there must be something up here. Thought you may be “adding another” to a seperate column as it were. Got 4000 vs 100. That’s when I saw my mistake. Very nice illustration Idle
