There are six toll booths B, C, D, E, F and G. Traffic moves from A to H. Transport and Road authorities can make changes in the rates of toll according to the requirements to manage the traffic. People always follow the routes that are the cheapest in travelling costs. The numbers given in the diagram are the travelling cost from one point to another. For example, the travelling cost between toll points B to C is Rs. 2.

To maintain equal traffic on all the routes, what would be the minimum cost of toll G to travel from A to H? (Assume the minimum toll at any booth will be Re.1)
