Infosys co-founder NR Narayana Murthy said on Thursday that the Indian economy is growing at 6-7 per cent this year and "investor confidence is at a historic high", news agency ANI reported. "India has become the software development centre of the world. Our foreign exchange reserves have crossed $400 billion," the IT czar said while speaking at an event in Gorakhpur. The comments from Mr Murthy come at a time when the economy is facing its worst slowdown in nearly five years, with some sectors staring at lakhs of job cuts.
