Only four women among India's 100 richest

The Forbes list of 100 richest Indians this year features only four women, including O P Jindal group chairperson Savitri Jindal and Biocon Chairman and Managing Director Kiran Mazumdar-Shaw. 

Anu Aga of the Thermax group and Indu Jain of Bennett, Coleman & Co are the other two women on the list.

The four women have a collective wealth of $11.3 billion and account for a little more than three per cent of the total net worth of all on the coveted list whose collective wealth amount to $346 billion. 

Jindal has retained the tag of being the richest woman in India with a net worth of $6.4 billion, according to the annual India rich list compiled by Forbes.

"After a three-year decline Savitri Jindal's O P Jindal group, which she chairs, has revived, mostly due to moves by Mumbai-based son Sajjan," Forbes said.

Jindal is ranked 12th in the list topped by Reliance Industries Chairman Mukesh Ambani with a fortune of $23.6 billion. 

She is followed by Jain, who was ranked 31st with a net worth of $2.6 billion. Biocon's Kiran Mazumdar-Shaw and Anu Aga of Thermax group have been ranked at 81 and 94 with a net worth of $1.2 billion and $1.1 billion, respectively.

"Kiran Mazumdar-Shaw aims to more than double its revenues to $1 billion by 2018," Forbes said.

On Anu Aga, Forbes said she had regained her "billionaire status" on jump in shares of engineering firm Thermax, in which she owns 62 per cent with family.

Since last year all the four women have been witnessing a spurt in their fortune.

Savitri Jindal's net worth increasing by $1.5 billion, for Indu Jain it was $700 million, for Kiran Mazumdar Shaw it stood at $545 million and for Anu Aga it was $370 million.
