I am confused that what should be the cost of the blog mentioned , hope you all help me. Thanks in advance for your suggestions
The thing is anything is worth only as much as what somebody wants to offer for it. It looks like a good blog. I think you should provide more stats (PR, daily traffic, etc.) before anyone can really assess its worth.
I think it is a very good website, PR1 as I can see, alexa : 274,672. I think it is good and it has a big potential. But I agree that people should see traffic and earnings to judge on how much it is worth.
I don't think you should sell it now, keep working on it and try increasing your earning so you could really sell it for what it is worth. Btw I really like the blog Could I suggest something? The horizontal ad above you should either go for a wider one or remove it.
