Post Test Your Brain 
 
This is really interesting. It's kind of a brain teaser.

Condition : You must do this in your head. Don't use paper to write out the problem.

Take 1000 and add 40 to it. Now add another 1000.
Now add 30. And another 1000.
Now add 20. Now add another 1000. Now add 10.

What is the total?



Spoiler: [ Show ]


Thanks.
