Finance Minister Pranab Mukherjee exuded confidence that the economy would soon revert to 9 per cent growth,witnessed in the pre-crisis period,even as industrial growth plunged to a 16 month-low of 4.4 per cent in September. The Finance Minister said the challenge now is to find the means to cross the double-digit growth barrier in the coming year or two. "In the short term,it is reasonable to expect that the economy will go back to the robust growth path of around 9 per cent average that it was on before the global crisis slowed (it) down in 2008," Mukherjee said at the India Economic Summit. Although manufacturing growth has slowed down in the past couple of months,the Finance Minister said the sector has been performing strongly.
