How do I go about solving questions based on routes and networks?

Hi Vinita, There is no one best way to solve routes and networks problems. But one good way of going about it is to try and eliminate possibilities by checking whether the conditions given in the question are being met at each node or intersection point. Try to select the node that has the least number of conditions imposed on it and start solving from that node. For example, in a question of traffic flow between different cities, if one of the routes allows traffic in only one direction etc., that would be an ideal starting point.

Also, always keep in mind the possibility of some parameter not taking a unique value. Questions with one of the options being 'cannot be determined' is quite common in these sets.

Thank You so much for the help Pv Aaditya..
