Oh yes, indeed its an easier method.
No offense taken at all
I am used to of solving tabular questions that are usually so complex that they cannot be done so easily, so I didn't even try to find out the simpler method and jumped to my "tried n tested" method (which actually is pretty quick for me, but may not be for others)
And I didnt see your method, because first i solved it my way, and found your answer not matching with mine. so i assumed (without checking your method) that you answered it wrong.
