It is expected to cross 87%. For now all we can go by is existing figures of 72%. Also India's tax to GDP ratio of around 20% (including central and the states taxes) covers for any such increase in public debt. That is the most relevant fact.
Given Pakistan's tax to GDP is only 10% and its overall debt has just crossed 100%, I would worry more about Pakistan than India.
Like I said, India shut down its economy for 3 months, because of pandemic. Because of which our economic transactions of this year (GDP) would fall. But next year, people won't be sitting at home in those lost 3 months. Those months will experience exorbitant growth of about 25%. And including the expected growth of 8% in other months, India would experience an overall real growth of over 12-13% next year. And nominal growth would be around 22%. So the lost GDP of this year, will be recovered in the next year or two.
