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
