yeah, I don’t get why it’s a teaser, either….

 

Take 1000 and add 40 to it.(1040) Now add another 1000 (2040). Now add 30.(2070) Add another 1000. (3070) Now add 20. (3090) Now add another 1000.(4090) What is the total? 4090

Did you change the original??? Now I swear it should end in an even hundred…. unless now I’m getting all mixed up.

Yeah the original was changed.  I think it’s a brain teaser because you’re supposed to do it in your head, and its easy to make the mistake of thinking it’s 5000 instead of 4100.

Ya, the original changed. She added the add 10 to the end. The total before the add 10 is 4090. When you add 10 to it the total is 4100 but our brains think it is 5000
