Answer» Total books in SPANISH = 8100 Sum of ratios = 4 + 3 + 2 = 9 No. of medical books in Spanish = (3/9) × 8100 = 2700 No. of other books in Spanish = (2/9) × 8100 = 1800 Total books in French = 33600 Sum of ratios = 7 + 5 + 4 = 16 No. of medical books in French = (5/16) × 33600 = 10500 No. of other books in French = (4/16) × 33600 = 8400 Hence, Total medical books in both languages = 2700 + 10500 = 13200 Total other books in both languages = 1800 + 8400 = 10200 ∴ Required ratio = 13200 ? 10200 = 22 ? 17 |
