Clan that controls the 90-year-old Bajaj Group saw its wealth increase by $1.3 billion, partly from the 70% rise in shares of financial services arm Bajaj Finserv. The group's financial-services business is overseen by Sanjiv Bajaj, younger son of 77-year-old chairman Rahul Bajaj, who shares fortune with cousins Shekhar, Madhur and Niraj. Motorcycle maker Bajaj Auto, run by patriarch's older son Rajiv, introduced the V15, a 150cc motorcycle partly made with metal from INS Vikrant, India's first aircraft carrier. The company has begun exporting Qute, a new 4-wheel "quadricycle" but is awaiting court approval to introduce it in India.
