Coming back to your question:
The maximum time the CPIO should reply is 30 days. However when the application is routed through ACPIO, they shall transfer the application to CPIO then in such case the application shall be processed in 35 days from the receipt of original application from ACPIO.
I recommend Mr.Jeevan to get hold of a copy of "The Righ to Information Act,2005 (22 of 2005), and go through it first. There are many in this Forum who will be happy to clarify your doubts provided to are willing to take some effort.
