Arunji,
There is a russian launch vehicle Start-1 based on the topol icbm. This consists of the three stages of Topol icbm + an extra small stage. It sends 632kg to 200km @52 deg, 395kg to 600 km @52 deg and 295kg to 800km@52 deg orbits. Now, this is still somewhat smaller than a 3 stage agni. Moreover, the topol stages have relatvely poor Isp Vac 263 for first stage, 280 for stages 2 and 3.
How much will a 3 stage agni send to 200 km leo ? By 3 stage you mean Agni V ?

~550 Kg payload to 200 km LEO, after accounting for ~180 kg for navigation and control avionics and batteries.
With following Agni configuration:
Payload = 750.0 Kg, Number of Stages = 4, Simulation Time Granularity = 0.100 Second
Launch Direction = 50 degrees-North, Launch Latitude = 22.00 degrees
