    Step-by-step explanation:

    Let the number of books be 6x,7x and 5x

    According to Question

    6x+7x+5x=1800

    13x+5x=1800

    18x=1800

    X=1800/18

    X=100

    6x=6×100=600

    7x=7×100=700

    5x=5×100=500

    therefore, the number of books of each subject are 600,700 and 500 respectively.

    Given :-

    • There are 1800 books in a library if the ratio of English , Maths and Science is 6:7:5.

    To find :-

    • The number of books of each subject.

    Solution :-

    • Total number of books = 1800
    • The ratio of English , Maths and Science = 6 : 7 : 5

    Let the English books be 6x, Maths books be 7x and Science books be 5x

    According to question

    → English + Maths + Science = 1800

    → 6x + 7x + 5x = 1800

    → 18x = 1800

    → x = 1800/18

    → x = 100

    Hence,

    • English books = 6x = 600
    • Maths books = 7x = 700
    • Science books = 5x = 500

    Verification :

    → English + Maths + Science = 1800

    → 600 + 700 + 500 = 1800

    → 600 + 1200 = 1800

    → 1800 = 1800

    • Therefore verified
