There are a wide variety of factors that make up Google's algorithm, which means it's difficult to pinpoint exactly why your specific blog pages aren't showing up. However, my first thought is that your query is too broad. Here's an example:
Pepsico is an internationally recognized company with a successful blog. Their blog pages are also indexed and presumably receiving good traffic. But if you search "Pepsico Blog," you're going to run into the same thing you're seeing. Instead of individual blog pages, you'll get their homepage, blog subdomain page and other more general search results. What you won't see is a specific blog post on, for example, their latest innovation projects.
Your individual blog pages are competing for the general search query "Fundsindia Blog" with other pages that Google deems more relevant to the searcher. If your homepage and blog subdomain are showing up first, that's a good thing. I would concentrate more of your efforts towards optimizing your individual blog pages for long-tail keywords, or post-specific topics/questions.
