Despite the international media being highly skeptical of these numbers, it may surprise you to know that I personally don't have an issue with the numbers.
Developing countries in general have a large amount of economic activity that doesn't find its way into official calculations, so it wouldn't surprise me if India and other developing countries are growing much faster than official numbers would suggest.
Considering India's base GDP per capita is lower than the developing world average, the new numbers aren't surprising. Having a lower base naturally means it easier to achieve a higher percentage rate of growth.
Also Modi's economic policies so far have been very good, with some extra breathing room afforded by the drop in global oil prices (and thus less of a problem with inflation, allowing more growth boosting measures).
Though it is funny how Indians always question China's growth rate, despite our economic indicators going up.
We've never had a year where our economic indicators have been falling hugely while our GDP growth rate has been soaring. Food for thought.
