Indian carmaker Tata Motors on Monday reported a 47 percent fall in quarterly profits after being hit by new struggles to sell its luxury Jaguar Land Rover cars in China and other key markets. Only increased sales in Britain and the United States helped offset falls in China, the company said. Consolidated net profit for the three months ending March 31 was 11.17 billion rupees ($160 million), down from 21.25 billion rupees a year earlier, said a company statement to stock exchanges.
