Mohandas Pai defended Infosys Founder Narayana Murthy's call for adopting 9-9-6 work culture in India, saying the latter isn't asking "ordinary people working in banks, offices and shops" to follow it. "It isn't for people who wake up at 11am and have tea," Pai said. "If young people...want to become billionaires...they've to do...one year's work in six months," he added.
