2)literature books = 650-562=88
Ratio =44:95

Answer 2

• The School has Total books=650.
• Number of Mathematics Books=200
• Number of History Books=172
• Number of Science Books=190
• We can assume number of books in Literature is=X
• So as per above information, X+200+172+190=650
• So X=650-200-172-190=88
• So Number of Literature Books=88
• Ratio of History books to all books in the Library=172:650=86:325
• Ratio of Literature Books to Science Books will be= 88:190=44:95
