Hello Mahesh,
yes if the AS path length is the same, the origin code is the same and the MED is the same BGP prefers eBGP over iBGP ( neighbor type).
Note: a missing MED is considered like MED= 0 by default.
The steps for BGP best path selection are the following:
1) the BGP next-hop has to be reachable = a route to the BGP next-hop must exist
2) the highest weight is preferred (this is Cisco proprietary and weight is not a BGP attribute and it is confined to a single device)
3) the highest local preference is preferred the local preference is limited to a single AS and it is a BGP attribute
4) Locally injected paths are preferred (in any way they are generated network command or redistribute). Cisco routers give weight 32768 instead of 0 to locally injected routes so this step in Cisco implementation is usually masked by step 2
5) the shortest AS path is preferred
6) the lowest origin code is preferred i better then e better then ?. In Cisco routers code i is given when network command is used , the incomplete ? is associated to the prefix when redistribute is used.
7) Lowest MED is preferred if comparable
8) neighbor type eBGP is preferred over iBGP, it is considered first hand information
9) lowest IGP metric to BGP next-hop if all routes are iBGP
There are other criteria and a lot of possible cases for MED.
see the following document for more details

BGP uses an ordered list of criteria to choice the BGP best path if previous steps do not provide a single best path it goes on looking at the next criteria in the list.
