How much maintenance should i pay

Hi, I am working as software engineer earning 1.5 lakh per month (after deducting tax, pf, etc). My wife has never worked but she has completed her b.tech in computer science. I was married on December 2021. She was very happy here, and never complained. Whenever she goes to her home, we used to talk and chat..but she always wanted not to stay with my family and wanted me to move to Bangalore. However i was having work from home option..so i did not leave my home. After 7 months, on June 2022 she went to her parental home and never returned. After more than 2 years, last month, on October 2024.. she has filed a false case on me and my family saying that she was not happy and tortured. she has also filed a maintenance case asking for 1 lakh rupees per month. I have all her photos for every month where we went outside or celebrated in home with family. Please can you tell me 1. How much maintenance will court ask me to pay? 2. What proof should i show to reduce maintenance if it is very high ? 3. Will court ask to pay maintenance on my CTC or the actual in hand salary which i get after deducting tax ? 4. All the allegations on me are false i have photo proof that she was not tortured anytime.. after this also should i pay maintenance? 5. Will she take maintenance for life long ? Please help me here
