Industrial production grew at four-month high of 3.8 per cent in June as manufacturing paced up.
"It (growth in IIP for the month of June) shows that the economy is on mend. It is consistent with the growth in indirect taxes," Mehrishi said.
Indirect tax revenue has also jumped over 37 per cent to over Rs 2.1 lakh crore in the April-July period this year on the back of higher excise duty collection.
Retail inflation fell to multi-year low of 3.78 per cent in July on account of cheaper food prices, including of vegetables, fruits and cereals.
The Finance Secretary said that retail inflation in the future should be well within reasonable limits.
"You can't predict these things (retail inflation) in the future but it should be under control. It should be well within reasonable limits. Whether it will be 5 per cent or 4.4 per cent its difficult to say but it should be reasonable figure, which is acceptable," Mehrishi said.
RBI on August 4 had spurned government's call to cut interest rates.
In the run-up to the August 4 bi-monthly monetary policy, the government had vociferously made a case for further lowering of interest rates, but RBI Governor Raghuram Rajan maintain status quo because of inflationary concerns.
