NEW DEHLI — When Narendra Modi became prime minister a year ago on a promise to revive India's once-sparkling economy, inflation was running at 9% and economic growth had slowed to less than 5% — half the pace of two years earlier.Today, inflation is down to 5%, and the International Monetary Fund forecasts India's economy will grow 7.5% this year, outpacing China's growth for the first time since 1999.
