### Solution :: Brain Teaser :: Can You Solve the Math Puzzle?

There was a pattern being followed and here is how we solve the puzzle row wise. The pattern was first add two numbers and multiply it by 2, the last digit in the product is where you replace the question mark with...

(3 + 2) x 2 = 10

(1 + 9) x 2 = 20;

Now here is the row in question::

(0 + 8) x 2 = 16

(7 + 5) x 2 = 24

Finally the answer to the puzzle was:: **6**

I guess this was not that tuff problem to solve and we had quite a lot of entries. All the entries provided the right answer. I am going to use a random picker tool to pick a random winner.
