India's wholesale price index rose 7.82 per cent in the 12 months to May 10, holding near the previous week's annual rise of 7.83 per cent, government data showed on Friday.
The rate was slightly above a median forecast of 7.77 per cent in a Reuters poll of analysts.
Inflation for the week ended March 15 was revised sharply upwards to 8.02 per cent from 6.68 per cent.
The annual inflation rate was 5.62 per cent during the corresponding week of the previous year.
The wholesale price index is more closely watched than the consumer price index, which is published monthly, because it covers a higher number of products and is published weekly.
