I want to know about the expenditure or Percent Expenditure of different Industries for Promotion activities in India? It would be great if I get specific data for Sales Promotion.
You could maybe read this kind of papers or try to contact the authors:
Mittal, M., & Sethi, P. (2011). The effectiveness of sales promotion tools among Indian consumers: An empirical study. Journal of Promotion Management, 17(2), 165-182
