Can you suggest a laptop in price range Rs 30000-35000?

As per your requirements, you should not go for Microsoft operating system. Your requirement will be better met with a laptop having an Ubuntu operating system. It should have i3 and or i5 7th Gen or above. Storage requirements won't matter much but having at least 500GB worth of HDD and 4GB or more RAM would suffice for you.
