Radha,
I would suggest you not to mention anything to your Boss right now, as things may not be same and you may not be able to acheive the same in the next 10 days. First reach your target and then you can inform your boss about it!
Also, if you really want to impress your boss, just finishing up the target is not going to work, may be some figure above the target can. you will have to be innovative and prove the management that you are thinking about the company's business and can present your ideas and concerns or ways (related to your work Profile) which would help the organisation and show your interest and initiative.
This will help you in the long run wherever you are!
Thanks
