Bihar produces _______% of pyrite of whole India?

This question was officially dropped by BPSC and full marks were awarded to all candidates. While the Amjhore mines in Rohtas district contain approximately 95 percent of India's total pyrite mineral reserves, commercial mining and active production of pyrite have been non-operational for years. Because Bihar's current production is virtually zero despite holding 95 percent of reserves, BPSC deleted the question due to the contradiction between reserves and production.
