I want to know the answer to the following question:
What percentage of Hyderabad city was covered by roads in 2012?
All the background I'm provided with is that "As of 2012[update], there are over 3.5 million vehicles operating in the city, of which 74% are two-wheelers, 15% cars and 3% three-wheelers.". Is that enough to answer the question?
Answer: no
