Hi, Zubair Ahmed!
I'd recommend you to read the three first green sticky topics at this forums main page. There you'll find general guidelines about how this site and community operates (introducing yourself, posting files, netiquette rules, and so on).
Among them you're prompted to perform searches within this site before posting, because maybe your question had been answered yet.
Feel free to play with different keywords so as to be led thru a wide variety of articles and posts, and if you don't find anything that solves your problem or guides you towards a solution, well, come back here, tell us what you've done, consider uploading a sample file as recommended, and somebody surely will read your post and help you.
And about your question, you say that columns are the same on all sheets and you're referring to rows as A, B, C, D and A, C, E, but this are column references. Could you please clarify this? Consider uploading a sample file as described in the green sticky topics.
Despite of that, the general formula for summing the same range in many sheets is like this:
=SUM(SheetFrom:SheetTo!RangeFrom:RangeTo)
where RangeFrom and to might be cell references (A1:B10), row references (1:10), column references (A:B).
Regards!
