IIT Delhi, which currently has a total endowment reserve of Rs 350 crore from its alumni, looks to add another Rs 250 crore in the next two years, its dean of alumni relations PVM Rao said. Last calendar, the institute raised about Rs 50 crore. “However, one big donation may change these projections as it happened with IIT Bombay with (Nandan) Nilekanis donation,” Rao said.
