One want 55 mill $
Normaly all 272 right now in order modernized in Super Su-30MKI
HAL build about 18/year, for a Sqn.
40 millions seems much but can include weapons especialy new BrahMos-A ?
A things is sure with 200 Mig-21/27 retired soon even with 36 Rafale ? T-50 for later 2020+ IAF need more Su-30 at less 40 as annouced these last time and build by Russia more fast to get.
Idealy more, 126 as planned for initial order planned for Rafale less 36, so 90.
Max 36 Rafale seems but don' t change problem for India quite sure Dassault can 't delivered much with last orders Egypt, Qatar remains about 40 French minimum and time necessary for HAL for build no comments...
