Hello, I'm a pre-college American student currently situated in Romania. You haven't provided any details on what genre(s) of articles you want written, but I can assure you that I am a fantastic writer, and can adjust to any assignment well.
50 INR per article isn't very much, it isn't even 1 USD. I'd be willing to work for about 5 USD per article, but it really depends on what they are about.
I am also very knowledgeable when it comes to anything computer-related, so if you have technical articles in mind, I'm the man for the job!
