Mind twister

This exercise must be done in your head only . Do NOT use paper and pencil or a calculator. Try it!
Take 1000 and add 40 to it. Now add another 1000 . Now add 30 . Add another 1000 . Now add 20 . Now add another 1000 Now add 10.

What is the total?

Did you get 5000 ?


Correct answer is 4100!!!

I tried paper and I still get 5000. I must be brain-damaged.

Hello mtm, the same happened to me. So weird!!!! Welcome to Tallouza!


At the final step, when you add 4090 and 10, it will give 4100... but our mind will automatically take it as 5000...
