India\'s economic growth slowed to a worse-than-expected 6.1 percent in the final three months of 2011, data showed Wednesday, hit by a string of interest rate hikes and a sluggish global economy. The figure for the financial third quarter was below market expectations of 6.3 percent expansion and comes on the back of 13 interest rate hikes since March 2010 that have sapped demand and slowed manufacturing activity.
