Cst clarification needed

I have a query for which I have not been able to receive any answer when browsed on internet. Here is the question:

I am a registered Dealer in Karnataka.

I am procuring products (Sweets) from Rajasthan and Selling it in Mumbai. The products will be directly shipped and will not land in Karnataka. The invoice will be in my company's name.

My purchase price will be Rs. 350

I want to make Rs 30 as profit.

What should be my selling Price inclusive of all taxes?

Detailed calculations on how taxes are calculated will help. Looking forward to response eagerly.

Regards,

Jagadish
