Tough Interview Questions: Add All the Numbers Between 1 and 100

You can’t just sit there and have a mental column in your head and start going, “one, 3,6, 10 …” There is just no time for that.  They’re not going to just sit there while you go through this routine.  So, what’s the answer?  How do you figure this out?

If you think about it every individual member has an opposite reciprocal number that adds up to 100.  For example, 99 and 1.  98 and 2.  97 and 3. 

On and on and on.

When you realize that 50 pairs had to up to 100, you have 5000 (remember, you have 100 and 0).  But, there is one number that doesn’t have a parent – – 50.

So the answer becomes 5050. 

So, again, there’s always a trip to the question that you are asked, especially with the math ones.  So, this is the trick for any all the numbers from 1 to 100.
