Corporate Website and Word press Blog

I am using wordpress based website and Blog too now my query is can i post same content on two places…like

abc.com this is my site(cached and ranking well and properly indexed
abc.wordpress.com where all my blog posts …now i all my blog pos are on my website like

abcdotcom/blog

so two place same content any issue with indexing, crawling or ranking or block my abcdotwordpressdotcom blog

Yes, it will be considered as a duplicate content and will surely not benefit but if you are using same topic but with better information on the second one with unique content, it will be beneficial.

Google wont like it at all. Anything duplicated like that will be more than likely taken off of any google search results and banned. You would be better off using feed for the blog.

Duplicate content will hurt your rankings for both sites. You should make sure that one of them is blocked.
