Slightly incorrect. Th IA has ordered 114 LCH, a number which corresponds to roughly 10 light attack helicopter squadrons, each with 11-12 helis . It is to be noted that each Corps (Rather group Armies) will in time get integral aviation brigades, with a squadron of light attack helis each. In short, the minimum number of LCH to be ordered will be 154-168 for the IA alone (14 corps).
The IAF has already issued a requirement for 65 LCH. Summarizing, that's 179 LCH confirmed, and another 40-54 LCH to be added to the order book at the minimum. As for Rudra, 76 has been confirmed for IA-IAF combined, with the Navy expressing interest in 20.
The IA has expressed a need for 39 Apaches, at 13 per Strike corps to form the heavy attack helicopter squadron for the I,II & XXI Strike corps. However given that the newly raised XIV corps is designated as a Strike Corps(Mountain), it is likely to hold a heavy attack helicopter Squadron as its integral strike asset. That would be another 13, for a total of 52.
Summary:
LCH: 179(confirmed)+54-64(logically expected) = 233-243
ALh-WSI (Rudra):76(confirmed)+20(Navy Interest) =96
Apache: 22(IAF)+11(follow on for IAF)+39(IA)+13=85
These numbers represent the expected force levels given current operational planning. When the Amphibious/expeditionary force is raised formally, additional orders will be expected for operations from on-board LPD/LHDs in fire support roles
Edit: There is a bit of confusion about the number of attack helicopters in an attack helicopter squadron; it should be 12 per squadron, but the IAF has ordered 22 apaches @11 per squadron.
