PM Salary in Mumbai? 3Yr+ exp in PM

Given high cost of living, I’ll be guess a ballpark number between 25 to 35 lpa.

It depends more on company and not on the city TBH. A good product company will pay high anywhere

Yes expect them to pay you well. Mumbai is costly. Should be at least more than 25 lacs to have a decent life if you are a bachelor, more than 35 lacs, if you are married
