Billionaire industrialist and India's richest Mukesh Ambani has not taken a pay hike for seven years, but his salary is over 205-times that of the median employee remuneration at Reliance Industries Ltd . The same ratio stands much lower at 89-times in case of IT major Wipro's Chairman and Managing Director Azim Premji, and just at 19-times for mortgage giant HDFC's Chairman Deepak Parekh for the latest fiscal 2014-15.
