The HSBC composite purchasing managers' index for India compiled by S&P Global rose to 62.2 in April from March's final reading of 61.8. The reading of 50 on the index marks the dividing line between expansion and contraction in the economy.



"The rise in new orders was driven by strong performance in both the manufacturing and services sectors, resulting in the highest composite output index since June 2010," said Pranjul Bhandari, chief India economist at HSBC.



Services activity led strong expansion, with the index rising to 61.2 from 61.2 in March due to an acceleration in new business growth.



The manufacturing PMI continued strong growth in March to 59.1 in April due to an increase in output as well as new orders for goods.



An increase in output to meet rising demand helped boost job growth, especially in the manufacturing sector, which grew at the fastest pace in a year and a half. However, according to the survey, job creation in services was slightly slower than in March.



Overall international demand was solid and the overall sub-index reached its highest level since September 2014, when it was first included in the survey.



Strong sales have also improved the business outlook for the next 12 months.



"Manufacturing margins improved in April as companies were able to pass on higher prices to customers due to strong demand conditions," Bhandari said.
