How much do top executives in Kerala's local companies earn?

I'm interested in knowing how much top executives in Kerala-based local companies earn. The skill set required to be a successful executive in such companies—like V-Guard Developers—seems quite different from that of a VP of Engineering at a tech firm. It involves a deep understanding of the local market, language, culture, and political landscape, making it difficult to transfer directly to a similar role in another country or city. I'm not interested in the earnings of founder-family members (e.g., Muthoot, V-Guard), as those are often shaped by internal accounting rather than reflecting true executive compensation. Public companies, on the other hand, have boards of directors and market data that set compensation benchmarks, so their salaries are more predictable. What I find more intriguing is the earnings of division heads or senior leaders in companies like Lulu Malls, Skyline Builders, or Eastern Group. If you have any insights—especially if you know someone personally—it would be great to learn about their career paths and educational backgrounds.
