A tannery extracts mangrove barks containing 4%moisture, 37% tannin, 23% soluble non-tannin material, and the rest are the insoluble non-tannin material. The residue removed from the extraction tanks contains 62%moisture, 2.8% tannin and 0.95 soluble non-tannin material. What percentage of the tannin in the original bark remains unextracted in the residue?
