Only notebook available in India below Rs.10000 is Wespro 7" Mini Laptop Win CE. I didn't use this laptop but from the comments from user the laptop is good for browsing internet. Browsing in the sense you can just view the content. I don't think it can run office apps like Microsoft Word. Getting notebook below Rs.10000 is not possible. Basic desktop processor will cost you Rs.3000 and if you add other mandatory hardware like RAM, hard disk and display, it will obviously cross Rs.10000.
Starting price of Notebook is Rs.17000. If you are lucky you can buy it for Rs.15000 using offers. If you want to buy a device for below Rs.10000 then you should go for mobile device. Tablet is a mobile device where you can get it for below Rs.10000.
You can use tablet with keyboard for typing and internet browsing. Drawback in tablet is you only have less space. However you can use Google drive for additional space requirements.
If you can shell out extra Rs.5000 go for notebook or buy a tablet with keyboard which is doable under Rs.10000.
