I found a laptop for Rs. 31,490 on amazon for you:

http://www.amazon.in/Dell-Vostro-V3446-14-inch--Windows/dp/B00KQK94OW/ref=sr_1_3?s=computers&ie=UTF8&qid=1417224757&sr=1-3&keywords=Dell+Vostro+V3446

It has:

1. 2GB Dedicated Graphics 820M
2. 4th Gen Core i3
3. 500GB Hard Drive
4. 4GB RAM
5. Optical Drive

Unfortunately, it does not have a backlit keyboard, but it is well under your budget so maybe you can look past that.
