Maintenance demand from wife living seperate.

Hello sirs, I am a engineer working in a psu getting 65k salary net. Having liability of car loan and insurance premiums for self. Also have a land in my name purchased before marriage but registered aftwr marriage. My marriage was held in 2012 after some personal issues my wife left my paternal house in 2015 while I was working very far from home. Then she immediately filed 498a, DV and 125 for maintenance. After suggestions of our advocate we also filed for RCR in 2016. Now I have recieved a notice to appear in the court of wife's place of maternal house for demand of maintenance of Rs.40k from my wife. She has falsely alleged that I have a shop in my name and in total I earn approx 1.2lacs per month. She has shown herself having no job. She is M tech in computer science and was teaching in govt. College before leaving my paternal house and has previous worl experience as well in teaching but has puropsely not doing job and left the job before filing cases against me and my family. Now my questions are as below: 1. Can she by any means come to know about my salary from my company and also can I be suspended if she sends such details of cases filed against me to my compamy. 2. Can I get the cases transfereed to my place of working or my hometown where incidents took place as I currently work 1500kms away from hometown and it will be completely disastrous for me to spend so much money and time to go fight these cases this much far while paying for maintenace to her and cost of fighting cases. 3. How much can she demand ethnically for maintenance being overqualified than me as well. And would it be good to settle for one time or monthly maintenace please advice. 4. Can i deny maintenance on the grounds of not responding to RCR notices and desertion of my paternal house without any information.
