Hi Sumeet,
what is that number you posted with your name? Telephone? If that is so, I'd recommend not to put it into your signature but to have it just in your profile. Same goes with email addresses & other links. Just put them into your profile where everybody can find them (if interested).
About your question: your question is a pretty newbie question for a modeling/SQL/database query forum. But instead of marking it as "failed to search" I'd rather want you to get a little bit more involved.
First off: the way you backed up your question with example data is much better than what we often see here.
Well done - that way everyone clearly sees what you want to achieve.
What's missing however is that you show us, what's you've tried to so far and why it didn't solve your problem.
Why do you think that this cannot be done in graphical calc. views? What have you tried so far?
How would you do it in SQL?
Ok, your turn 
- Lars
