NRI steel tycoon Lakshmi Mittal (USD 16 billion) also continued to hold the second position, while Sun Pharma's Dilip Shanghvi has jumped to third place with about 50 per cent surge in his wealth to USD 13.9 billion, pushing IT mogul Azim Premji to fourth place (USD 13.8 billion).
As per US-based business magazine Forbes' annual list of India's 100 richest, their total wealth grew by a modest 3 per cent from a year ago to USD 259 billion. "Growth in wealth was lacklustre due to India's stumbling economy, which has been hit by inflation and a falling rupee," Forbes said.
Moreover, Pallonji Mistry, patriarch of construction giant Shapoorji Pallonji Group which is the biggest shareholder in Tata Sons, has moved down one place to fifth rank with a networth of USD 12.5 billion.
Besides, NRI businessmen Hinduja brothers have moved up to sixth place (USD 9 billion), from their 9th position last year.
Shiv Nadar (USD 8.6 billion) have moved into top-ten at the 7th place, while Sunil Mittal has also returned to this league at 10th place (USD 6.6 billion). On the other hand, Essar group's Ruia brothers and Jindal group's Savitri Jindal have moved out from the group.
