Planned sibling's wedding in vrindavan, was costing around 15L for 2 days 175 people. (1st day breakfast and lunch was for 75 people) and second day (150).
The venue had some type of donation system too (idk remeber correctly) and it would've been deducted in ITR as donation.
This cost is just for venue (and venue related expenses like decor stay and food), total wedding cost in this case would go beyond 25L without gold.
Visited a wedding in Orchha last month, for 200 people 2 days, it must've costed around 25L for venue only.
Got quotes from some venues in dehradun and jim corbett region all in the ballpark of 15-20L.
