I want to know the answer to the following question:
In 2012 what percentage of Hyderabad freight was moved by road?
All the background I'm provided with is that "The large number of vehicles coupled with relatively low road coverage—roads occupy only 9.5% of the total city area:79—has led to widespread traffic congestion especially since 80% of passengers and 60% of freight are transported by road.:3 The Inner Ring Road, the Outer Ring Road, the Hyderabad Elevated Expressway, the longest flyover in India, and various interchanges, overpasses and underpasses were built to ease the congestion.". Is that enough to answer the question?
